Question

A 12-sided die is rolled. The set of equally likely outcomes is

{1,2,3,4,5,6,7,8,9,10,11,12). Find the probability of rolling a 4.

Answer 1

Answer: 1/12

Reason:

There's one side we want (rolling the "4") out of 12 sides total. Each side has a probability of 1/12 of occurring since each side is equally likely.
