What is the probability of throwing a 2 on a dice?

What are all the possible outcomes of rolling 2 dice?

Note that there are 36 possibilities for (a,b). This total number of possibilities can be obtained from the multiplication principle: there are 6 possibilities for a, and for each outcome for a, there are 6 possibilities for b. So, the total number of joint outcomes (a,b) is 6 times 6 which is 36.

What is the probability of getting an even sum of score in a throw of 2 dice?

Thus, we have P(even sum)=1/2(P(first was even)+P(first was odd))=1/2(1)=1/2.

What is the probability of rolling a 7 or 11 with two dice?

The probability of winning on the first roll is the probability of rolling 7 or 11, which is 1/6 plus 1/18, which equals to 2/9. Suppose we roll 4 on the first roll (the probability of rolling 4 is 1/12). On each successive roll the probability of rolling 7 is 1/6 and the probability of rolling 4 is 1/12.
