Question

Amy and Betty roll a fair cubical die numbered from 1 to 6. Find the probability that Amy rolls a higher number than Betty?

Answer 1

Answer: 5/12

Explanation:

6x6=36

36 is all possible values.

1+2+3+4+5=15

The higher the number betty rolls there will be one less possible value that will be bigger than hers.

15/36=5/12
