Question

A regular number cube is rolled. What is the probability that a 3 will not be rolled?

•1/6
•1/2
•4/5
•5/6

Answer 1

5/6

Explanation:

Answer 2

5/6

Explanation:

probability(event) = (number of desired outcomes)/(total number of outcomes)

The total number of outcomes is 6 since there are 6 different sides on the cube.

The number of desired outcomes is 6 minus 1 for rolling a 3, so it is 5.

p(not 3) = 5/6
