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
