Question

If two fair dice are​ rolled, find the probability that the sum of the dice is 6​, given that the sum is greater than 3.

Answer 1

You have to make table of the sample space

1,1 1,2 1,3 ... 1,6

2,1...............2,6

3,1................3,6
4,1
5,1
6,1

You should have 36 entries.
Given the sum is greater than 3 will eliminate 1,1 1,2 and 2,1

So you are working with 33 possibilities for the denominator

The numerator will be the number of times you find 6 as the sum in your table.

Answer 2
