How many ways are there to get a sum of 9?

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.

When two dice are thrown simultaneously What is the probability?

We know that the total number of possible outcomes when two dice are thrown is =6×6=36. We know that the probability of any event is the ratio of the number of favourable outcomes and the number of possible outcomes.

What is the probability of getting a total of nine?

How many ways can we get a 9 with two dice? 936 , which can be simplified to 14 . Therefore, the probability of rolling a 9 with two dice is 14 .

How many different ways can you roll a sum of 10?

The number of ways of getting a sum of 10 is (6, 4), (4, 6), (5, 5). A sum of 10 is obtained 3 times.

What is the probability of getting at least one?

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).

What is the probability of getting 1 and 5 If a dice is thrown once?

So they are mutually exclusive events, therefore their probabilities add to 1. By symmetry we expect that each face is equally likely to appear and so each has probability = 1/6. The outcome of a 5 is one of those events and so has probability = 1/6 of appearing.
