A number cube with the numbers 1 through 6 is rolled.

Find the probability of rolling a number different from 9.

1. 1/2

2. 1

3. 2/3

4. 0

Step-by-step explanation:

Given that, we have a number cube label 1,2,3,4,5 and 6.

Then, the sample space is

S = {1, 2, 3, 4, 5, 6}

The probability of rolling a number different from 9?

Since we don't have 9 in the sample space, then the probability of rolling a number different from 9 will be the have 1,2,3,4,5 and 6 as the outcome

Then,

Pr (rolling number different from 9) = 6 / 6 = 1

Pr (rolling number different from 9) = 1.

The second option is correct.
