The probability of a certain event is a number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences. In mathematics, it is a measure of how often an event will happen and is the basis of statistics.

The ratio of the chance of that event happening divided by all possible events. Chance of rolling a 6 is 1 (only one side has a 6) divided by the 6 possible events.

There are 6 sides of a die, and rolling a 3 is one of the 6 sides. Therefore, there are 5 sides on the die which is not a 3. So, (outcomes wanted)/(total outcomes)=5/6

The same as anyone else. No genetic marker has been found yet related to identical twins.

No. Standard deviation is not an absolute value. The standard deviation is often written as a single positive value (magnitude), but it is really a binomial, and it equals both the positive and negative of the given magnitude. For example, if you are told that for a population the SD is 5.0,...

The set of X 1 , X 2 , ..., X N is called X. Given that mean(X), is the sum of all X divided by N, the variance of X is mean((X i - mean(X)) 2 ). The standard deviation of X is the square root of the variance.

Natural marble is best for kitchen flooring.

There are 36 permutations of two dice, with totals ranging from 2 to 12. Of those, only 6 permutations, 4-6, 5-5, 5-6, 6-4, 6-5, and 6-6 are greater than or equal to 10. The odds, then, of throwing 10 or higher is 6 in 36, or 1 in 6. The odds of throwing less than 10 is 30 in 36 or 5 in 6.

The probability of NOT drawing a spade from a standard deck of cards is 75 is an example of a mistated question - a standard deck of cards is 52, not 75.

By the pigeonhole principle, the answer is 100%

The question has been truncated. I suspect it either should end: "...none of the calculators work," in which case: for all 3 to be faulty the probability is 1/10 Ã 1/10 Ã 1/10=1/1000=0.001=0.1 % or: "...none of the calculators are faulty," in which case: for all 3 to not be...

Each dice has 36 possibilities. Find 36 to the power of 6 and theanswer should be 2176782336.

3c2+2c2+3c1 2c1 --------------- 7c2. I have done it this way. 3C2 means that the both balls would be green 2C2 both would be red and 3C1 and 2C1 because both the balls can be red and green.

No, in euchre, and in almost all card games, you deal to your left.

By the definition of standard deviation, 95.46% of the normal population will be within 2 SD of the mean. Explanation: The normal distribution of a population means it follows the "bell curve". The center of this bell curve is the population's mean value. One standard deviation defines two areas ...

the standard error will be 1

Of the first 10 positive whole numbers, 2, 4, 6, 8, and 10 areeven. So 5 in 10 or 50%

25 marbles=7 blue + 4 green + 8 red + 6 yellow The ratio of blue to yellow marbles is 7:6

With a fair coin, it's (1/2)^10 or 1 in 1024.

it can be used when members of the population are heterogenous

The probability of rolling a number greater than 8 on one roll of a pair of dice is 0.277777... . Let's see how we get that probability, and, though it may be a little long winded, it's important to understand what's going on. With one roll of a pair of dice, we have 36 possible outcomes. They...

There are four aces. The ace of clubs (black), the ace of spades (black), the ace of diamonds (red), and the ace of hearts (red).

Lightening was the probable cause of the power shutdown. It is probable that the economic situation will deteriorate. I think lightening is the cause of the bad power .

If a fair coin is tossed 5 times, the probability of getting 5 heads is: P(H,H,H,H,H)=(1/2) 5=1/32=0.03125=3.125% â 3.1%

We'll if they are 89% it's pretty high

If the deviation is small ie if the distribution is packed close to the mean.

Prob(less than 5 on a roll of a die)=4/6=2/3

Assuming the die is fair, the probability of a number greater than three is a half so the EXPECTATION would be that it will land on a number greater than 3 thirty times. But, this is the expectation; the actual number could be anything from 0 to 60.

Probability is 1/8 or 0.125 or 12.5% Explanation: A fair dice with six sides (numbers) has a probability of 1/2 of rolling an even number. Note: 1/2=3/6, where the dice has 3 even numbers out of six total sides. The probability of three same dice all roll an even number is the probability...

There is no answer to that really, but, if your husband/boyfriend/fiance/ male has fathered children, example 3 girls, you may have a higher chance of having a girl, or not, since you are a different mother. thank you

The formula for standard deviation has both a square (which is a power of 2) and a square-root (a power of 1/2). Both must be there to balance each other, to keep the standard deviation value's magnitude similar to (having the same units as) the sample numbers from which it's calculated. If...

The odds of choosing a prime number in the set [1-20] are 8 out of 20, as there are 8 prime numbers, 2, 3, 5, 7, 11, 13, 17, and 19, in that set.

In a normal poker deck, a total of 26 cards are red. This is half of the cards (two out of the four suits).

Independent events.

First of all why are you pacing... but if you are then i'd feel mad and angry

To keep it simple and not get too technical, fraternal twins arefrom two eggs and two sperm that independently combine to produce ababy. Identical twins come from a single egg and sperm that divideto create two separate children. Gender is controlled by the malessperm and whether it contains the...

Likelihood is 1/52 or approximately 1.9%. This is based on: (1) a standard deck has 52 cards, and (2) a standard deck has only one king of clubs. So the chance of drawing that one card out of all 52 cards, on one try is: 1 divided by 52.

First of all, the total will be 16. 6/16 - Mound 5/15 - Milky Way It's 15 because you ate one. Hope this helped.

Bag with 10 marbles: 3 orange, 5 black, 2 white. Rephrasing the question. If a marble is drawn from the bag, then returned to the bag, and a second marble is drawn, what is the probability that the first marble turns out white and the second marble black ? The probability for a marble to come out...

The probability is 100%. There's no way to take four marbles out of this bag without at least one of them being white.

When your driving and you have tow routes you can take, one with red lights that shorter, and one without red lights and is longer. You try and figure out the probability that you will hit the lightes all green and make it sooner, or go the long way and not chance it. Also the chance that you'll be...

p/(1-p) the relation between both outcomes.

It Is Called An Outcome :) ( YOur Welcome)

since rolling a dice can give you 36 possible combinations, there are 1/9 chances that you will get a sum of 5. 1+4 2+3 3+2 4+1 the 4 equations above will produce a sum of 5 so,the probability is 4/36, or 1/9.

If you put all your effort in, then probably 100%. Some things guranteed, are really hard for sure, but no one really said it was impossible. A bucket list is meant to be completed or achieved, like life's goals. They are not written to be just thrown out as some stupid list, it's meant to be...

The best way to think about this is the following way: What is the probability of flipping heads once? 1/2 What is the probability of flipping heads twice? 1/4 (1/2 * 1/2) Using this we can derive the equation to find the probability of flipping heads any number of times. 1/2 n Using...

You would be more likely to pull out a white marble as there are no red marbles in the bag.

It means that 95% of the values in the data set falls within 2 standard deviations of the mean value.

Well, if there are 52 cards in the deck, the probability will be 4 / 52 , which is 1 / 13. If there are Jokers in the deck, there will be 54 cards, so the probability will be 4 / 54 , which is 2 / 27 . Hope this helps!

To determine probability you do Number of Times the Desired Event will occur -------------------------------------------------------- Number of Possible Outcomes In this case, there are 52 cards in a deck (assuming no jokers). 1/4th of those cards are spades (This gives us 13 spades) so Number...

False. In order for the line PQ to lie in plane B, then both P and Q must lie in plane B.

The probability of rolling a sum of 11 with 2 dice is: P(11)=1/18 . For explanation see answer to question: "What is the probability of rolling 7 or 11 with 2 dice?". Read more: http://wiki.answers.com/Q/What_is_the_probability_of_rolling_7_or_11_with_2_dice#ixzz1vlcEp8K0

If something is certain, then the probability of that something is 1.

Assuming these are six sided dice, there should be 4 ways to roll a sum of 5. 1 + 4=5 4 + 1=5 2 + 3=5 3 + 2=5 There are 36 (6^2) possible combinations of rolling two six sided dice. That should mean 4 out of 36 rolls should give us a sum of 5 or reduced to 1/9.

Find the possible combinations of rolling a six with two dice: 1 + 5=6 5 + 1=6 2 + 4=6 4 + 2=6 3 + 3=6 3 + 3=6 Six in total. Find the number of possible combinations; Number of Sides on the Dice (6) to power of how many dice (2)=36 Number of Times the Dice will sum to Six (6 times)...

There are 2 red suits and 2 black suits. Therefore the probability of drawing a red card is 1/2. Or 50% chance.

You should ask the dealer what the proper indication is. Usually the desire to be hit in Blackjack is indicated by bending a finger towards you, in a "come here" sign, or by pointing down at the cards, but this could be confused with the stay command which is usually a flat open hand over the cards....

Not even is odd. Odd is 1,3,& 5 which is 1/2 of the numbers on the die. Therefore the probability of not rolling an even number is 1/2 or 0.5.

1/6 x 1/2=1/12. 1/6 x 1/2=1/12. 1/6 x 1/2=1/12. 1/6 x 1/2=1/12.

The probability of getting heads on three tosses of a coin is 0.125. Each head has a probability of 0.5. Since the events are sequentially unrelated, simply raise 0.5 to the power of the number of tosses (3) and get 0.125, or 1 in 8.

The probability of tossing a coin and getting heads is 0.5

The probability is 1 as all values on a die are less than 7.

in a deck of 52 cards there are two and four each of the number cards one over ten the probability of picking a joker is two out of 52 our two 52 write as a fraction the probability of drawin a 7

you toss 3 coins what is the probability that you get exactly 2 heads given that you get at least one head?

The only probable ion to form from Lithium is the Li + ion.

Prob( Number on one die is larger than that on the other)=1 - Prob(Number on both dice is the same). If the two 1s are distinguished as 1 and 1', then the favourable outcomes are (1,1), (1,1'), (1',1), (1',1'), (2,2), (3,3), (5,5) and (8,8) - eight of them in all. So 1 - Prob(Number on...

is this a question

Let X=the number of green marbles. X+3=the number of blue marbles. X + (X+3)=23 2X + 3=23 2X=20 X=10 or the number of green marbles.

No. Only the king, queen and jack are the face cards.

No; if twins are fraternal then they can't be identical.

A low standard deviation would mean that there is not much variation from the mean value of the data.

Let's break this down and see what we can do with it..First, the probability of transition of an atom from the initial state ( m ) to final state ( n ) will depend on what it is that is transitioning, and also on how it's transitioning. Which element - and which isotope - is transitioning? And...

An equal chance of being chosen? A simple random sample. (SRS)

It may or may not be acceptable. If the mean is 12, then no it is not acceptable. If the mean is 1000, then it may be acceptable depending on the criteria given.

simple random sampling method

There are four 4s in a standard deck of cards.

The chance of rolling it each time is (1/6). So the chance of rolling it 4 times in a row is (1/6) x (1/6) x (1/6) x (1/6)=(1/1296)=0.0007716=0.0772 % (rounded) The chance of rolling it each time is the same. It's not affected by what came before, since dice have no memory.

log 2 sqrt(q)=p/2 log 2 8q=3 + p And it is root, not route.

The mean is the average value and the standard deviation is the variation from the mean value.

The square of the standard deviation is called the variance. That is because the standard deviation is defined as the square root of the variance.

It happened for the first time in 2008. To calculate the probability you'd need to know the probability of each number 1 seed winning each game, and that changes every year (and can't really be measured).

The same basic formula is used to calculate the sample or population mean. The sample mean is x bar and the population mean is mu. Add all the values in the sample or population and divide by the number of data values.

Sample space for two coins tossed is: HH HT TH TT Therefore at most one head is HT TH TT or 3/4 or 0.75.

There are 4 sevens so probability of drawing a seven is 4/52 or 1/13 or 0.0769.

The distribution of sample means will not be normal if the number of samples does not reach 30.
