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 are the odds that when you roll two dice the sum will be greater then 5?
When you roll two dice the odds the sum will be greater than 5 are 13 out of 18, or
the probability is 13/18 = 0.72222... ≈ 72.2%.
The number of permutations of the numbers of the two dice which sum is greater
than 5 is 26:
(1,5), (1,6), (2,4), (2,5), (2,6), (3,3), (3,4), (3,5), (3,6), (4,2), (4,3), (4,4), (4,5),
(4,6), (5,1), (5,2), (5,3), (5,4), (5,5), (5,6), (6,1), (6,2), (6,3), (6,4), (6,5), (6,6).
The probability for each of the 26 events is 1/6 x 1/6 = 1/36.
So the probability that in a given roll of two dice the resulting event is any of the above 26 events is 26/36 = 13/18 = 0.72222... ≈ 72.2%.
What is the probability of pulling a red face card and another red face card out of a full deck?
26 of 52 because there are 52 cards in deck and half of them are red and the other half is black so half of 52 is 26 so there is a probability of pulling a red card 26 out of 52 cards.
What are the chances of drawing four 2 from a deck of cards?
P( four 2's) = (4/52)(3/51)(2/50)(1/49) = 1/270,725
The first one can be anything.
The next has to be 4/7, then 3/6, 3/5, 2/4, 2/3, 1/2
Hence the probability is (4 x 3 x 3 x 2 x 2)/(7 x 6 x 5 x 4 x 3 x 2)
= 6/210
=1/35

What is probability of getting 6 in a role of dice?
1/6, because there are six sides, so it would have to be 1 chance out of those six. :)
A student must answers 8 out of 10 questionshow many choices does the student have?
This is a combinations question. The answer is C(10,8), the number of combinations of 10 things taken 8 at a time, which also equals the number of combinations of 10 things taken 2 at a time. You can imagine why these are the same: choosing 8 questions to answer out of ten is the same thing as not choosing 2 questions to answer out of ten. C(10,2) = (10*9)/(2*1) = 45. There are 45 different choices the student can make of which eight questions to answer.
What is the chance of you selecting a king from a deck of playing cards?

What is the probability that you don't roll a sum of 3 when you roll two fair dice?
I think of it this way. Take it as two unique 6-sided dice, then you have 36 possible outcomes (6 times 6). Two of these outcomes will add to equal 3 (2 & 1, and 1 & 2), so there are 34 [36-2] outcomes which don't sum to 3. The probability is 34/36 or about 94.44 percent chance.
If you're asking what the probability you don't roll AT LEAST three is, the only roll on two normal dice less than three is two, and there's only one way to roll it: 1,1. So the probability of not getting AT LEAST three on two fair dice is 1/36.
