Probability

The probability of drawing two diamonds from a deck of cards is (13 in 52) times (12 in 51), or 156 in 2,652, or 78 in 1,327.

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.

As a coin has two sides, the odds are always 50-50.

the probability is 1 out of 6

Yes it is. That is actually true for all random vars, assuming the covariance of the two random vars is zero (they are uncorrelated).

You can't have furternal twins but what you can do is you can in make a sim you can make a child or whatever age you want but don't make a twin with it.. Then, make another child (or whatever age) and they should look different BUT they are the same age soo it's like they ARE furternal twins!! :) OR, have a kid then wait and have another kid and they will be different but the same age if you don't age them up:)

Hope that helped!! :)

There is a 13 in 52, or 1 in 4, or 0.25 probability of drawing a club from a standard deck of 52 cards.

If E(x) = 0.8, then the mean of the distribution is 0.8. You have not provided enough information to completely answer this question.

Prob(Rolling 2 when rolling 1200 times) = 1 - Prob(not rolling 2 when rolling 1200 times)

= 1 - (5/6)1200 = 1 [accurate to 95 decimal places]

That is, it is virtually a certainty.

7

There are 21 possible combinations of 2 dice. The total with the most possible combinations is 7, which has three. (6+1,5+2,4+3)

This is not right. By this logic 6 and 8 have equal chances of being rolled as I can roll a six through the numbers, 5-1, 4-2, 3-3. When counting the probability of a number to be rolled you have to assume the dice do not care the order in which they are rolled. That is to say, a roll of 5-2, and 2-5 are NOT the same. It is for this reason we find that 7 truly has many more ways a being rolled. 2-5, 5-2, 6-1, 1-6, 3-4, 4-3. While both 6 and 8 have less because one of their dice rolls cannot be counted twice the double roll. For six this is the 3-3 roll, and for eight its the 4-4 roll. That is why 7 is the most common roll on two dice.

The probability is 1. It is a certainty that you will roll a number between and including one and six. The probability of rolling each individual number is 1/6.

21

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.

four. king of spades, king of clubs, king of hearts and king of diamonds

No, it's a continuous distribution.

Yes.

unless your a hydra, in which case they should be reversed and translated into greek for calarity.

Yes, it is true; and the 2 quantities that describe a normal distribution are mean and standard deviation.

If the probability of an event is zero then that event cannot happen

Assuming a fair 6 sided die, there is a 1/6 probability for each number you could choose.

Pretty low, but it's higher than being in a plane crash.

Stay out of the street, and you'll probably never be hit, but drunk drivers are the most common cause of sidewalk car manslaughters.
