Probability
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.

What is the chance of not getting an ace from a pack of cards?
The chances are 12 out of 13 that you will not get an ace on the first draw.
What are the odds of throwing a six on a dice two times?

On just two rolls and if the die is fair, the probability is 1/36.
Do identical twins have to be the same sex?
Yes. Identical twins come from one fertilized egg that has been split in two. Therefore, whatever sex the single egg would've been, the twins will be.

You can draw any one of 80 different marbles.
Any one of 50 draws will be successful.
Probability of success = 50/80 = 0.625 = 62.5 %
In a standard deck of 52 playing cards what is the probability of drawing two ace on one draw?
0.45% (4 in 52) multiplied by (3 in 51) then multiplied by 100 to make a percentage ;)
He can and it is not.
You've described a couple of events, but we don't know the question.
That's like asking: Two boys and a girl got on a bus. What is the answer ?
How does the probability theory apply to statistics?
Statistics is the study of how probable an observed event is under a set of assumptions about the underlying probability distribution.
Pr(a sum ≤ 5 at least once in 3 rolls of 2 dice)
= 1 - Pr(a sum ≤ 5 never appears in 3 rolls of 2 dice)
= 1 - Pr(a sum ≤ 5 does not appear in a roll of 2 dice)3
= 1 - Pr(a sum > 5 appears in a roll of 2 dice)3 = 1 - (26/36)3
= 1 - (13/18)3 = 1 - 2197/5832 = 3635/5832 = 62.3% approx.
How do you do probability with dice?
Roll the dice and if you're doing to put it with fractions the denominator is 6
What set of seven numbers with a mean of 10 and a standard deviation of zero?
[10, 10, 10, 10, 10, 10, 10] has a mean of 10 and a standard deviation of zero.
How many different ways can you arrange the word This?
Since the letters of the word THIS do not repeat each other, the number of different ways you can arrange them is simply the number of permutations of 4 things taken 4 at a time, or 4 factorial, or 24.
No, I'm not going to list them, because that would trip Dingo-Bot for profanity. But you knew that, didn't you?
