To get a sum of 3, you must roll a 1 and a 2. To get a sum of 8, you must roll a 5 and 3, or two 4's.
There are two ways of rolling a 1 and a 2, two ways of rolling a 5 and a 3, and one way to roll two 4's.
There are

possible outcomes when rolling two such solids.
So the probability of getting a sum of 3 or 8 is
The product is the answer to a multiplication problem.
