Question

When rolling a fair number cube with numbers 1 through 6, what is the probability of rolling a number greater than 2?

A.) 1/2

B.) 1/4

C.) 2/3

D.) 5/6

Answer 1

You are asking for the proportion of numbers 1–6 that are greater than 2. The ones greater than 2 are 3, 4, 5, 6. There are 4 of them, out of the 6 possible numbers. Since the cube is fair, all numbers have equal probability. This means the probability of an outcome greater than 2 is

... 4/6 = 2/3

The appropriat choice is ...

... C.) 2/3
