What is the probability that a fair die never comes up an even number when it is rolled six times?

Each time you roll a die there is a chance out of 6 because there are 6 faces. Therefore because you rolled it 6 times

6 x 6 = 36

So it's out of 36

3 even numbers on a die

3 x 6 = 18

Your answer is:

18/36

Which can be simplified to:

1/2
