Question

A number cube is labeled 1 through 6. What is the probability of NOT
rolling a 2?

Answer 1

Explanation:

each of the 6 number has a 1/6 chance of being rolled

1 2 3 4 5 6

1/6 1/6 1/6 1/6 1/6 1/6

Every time the cube is rolled there is a 6/6 chance of any number comes up

1/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 6/6 or 1

What is the probability of NOT rolling a 2? Any other number

1 2 3 4 5 6

1/6 + 0 + 1/6 + 1/6 + 1/6 + 1/6 = 5/6 or 0.8333
