Since there are 6 numbers on a die (1-6), then the probability of rolling a 5 would be 1 out of 6.
There are three odd numbers in a die: 1, 3, 5. The probability of rolling an odd number in a fair die is: P(1 or 3 or 5) = 3/6 = 1/2
The probability of not rolling a 6 is 5/6.
rolling a die? 5/6
The probability is 1/6 x 5=5/12
