Problema Solution
A six-sided fair die and an eight-sided fair die are rolled together. What is the probability of getting numbers whose sum is a multiple of 3?
Answer provided by our tutors
There are 6*8 = 48 possible outcomes in this situation
The outcomes whose sums are a multiple of three are 16:
12, 21, 15, 51, 24, 42, 33, 18, 27, 36, 63, 45, 54, 48, 57, and 66
The probability of getting numbers whose sum is a multiple of 3 is:
p = 16/48
p = 1/3
p = 0.3333 or 33.33%
