Answer: see below

Explanation:

If this is a 6 sided die then the only possible roll that isnt an odd, a 2, or a 4 is 6.

The probability of something happening is also the probability of something not happening. So in order to not roll an odd, a 2 or a 4 in two rolls, you have to roll a 6 twice.

P = 1 - (1/6)(1/6) = 1 - (1/36) = (35/36)
