Question

List the sample space for rolling two dice and finding the sum of the numbers. How many 8's are there in the sample space? [Assume that rolling a 3 and a 5 is the same as rolling a 5 and a 3.]

A) 2

Answer 1

B!

Explanation:

An 8 will occur when you roll a 2 and 6, a 3 and 5, and a 4 and 4. There are 3 8's ine the sample space.

Answer 2

When you make the 6 x 6 table to show all of the combinations of rolling two six-sided die, the sums of eight will be:
2 + 6, 3 + 5, 4 + 4, 5 + 3, 6 + 2
Since we are not counting the 3 + 5 and 5 + 3 are two different combinations, there are 3 possibilities in the sample space.
