When two dice are thrown the total outcomes are?

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 a sum of at least 9?

❖ “At least one” is equivalent to “one or more.” To find the probability of at least one of something, calculate the probability of none and then subtract that result from 1. That is, P(at least one) = 1 – P(none).

How many ways can you roll a 9 with three dice?

So in total there are 25 ways to get a sum of 9. If you want the probability, just take this over the total number of possibilities and you get 25/63=25/216.

What is the probability of getting a sum greater than 9?

So probability of getting a sum greater than 9 is= 6/36=1/6 Ans.
