Question

If two dice are rolled one time, what is the probability of getting a sum of 9?

Answer 1

`1/9`

Explanation:

we need to know how many ways we can get `9`, and the total no of possibilities

there are 36 possible scores

and the following ways we can get `9" "`with two dice

`(3,6)" "(4,5)" "(5,4)" "(6,3)`

that is 4 ways

if ~X=#the sum of two dice

`P(X=9)=4/36=1/9`
