What is the probability of rolling two dice and it being composite?

Answer 1

There are 36 possible outcomes when two dice are rolled.

The composite outcomes and the number of corresponding events are:

4 - 3

6 - 5

8 - 5

9 - 4

10 - 3

12 - 1

So there are 21 outcomes out of 36 where the result is a composite.

So probability of a composite = 21/36 = 7/12 = 0.58333 or 58.333... %
