There are 6 possible outcomes, so the number of favorable outcomes will be divided by 6 to get your probability.

A) 2 can occur 1 time. P(2) = 1/6

B) there are 3 even numbers. P(even) = 3/6 = 1/2

C) 4 or 5 are 2 possible outcomes. P(4,5) = 2/6 = 1/3

D) there are 3 odd numbers. P(odd) = 3/6 = 1/2
