Question

What is the probability of rolling a sum of 8 or 6 on a pair of number cubes?

Answer 1

First, you need to know the sample space of rolling two dice, that is all the outcomes you can get. There are 36 possibilities:
(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)
(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)
(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)
(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)
(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)
(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

Answer 2

Now you need to figure out the probability of getting a sum of 8 form both dice
and the probability of getting 6

Refer to the sample space above to find that.
