Question

A single standard six sides die is rolled. what is the probability the roll is a multiple of three given that it is an even number

Answer 1

33.3%

Since we are given that it is an even number, we know there is only 3 options (2, 4, 6). Since only one of them is an even number, we know that we need the fraction 1/3 or 33.3% for a probability.
