Its 5/6 since we are excluding the number two (6-5=1)

A standard number cube has 6 sides, and so the numbers are:

1,2,3,4,5,6

P, is any of those numbers that are not 2.

2 is one of the numbers in 6, and so it is 1/6 of the die.

6/6 - 1/6 = 5/6

C) 5/6 is your chance of getting a number that is not 2


hope this helps
