What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem:

• There is a total of 32 numbers.

• Those that are divisible by 3, 5 or both are: {3, 5, 6, 9, 10, 12, 15, 18, 20, 21, 24, 25, 27, 30}, that is, 14 numbers.

Hence the probability is given by:

p = 14/32 = 7/16.
