Question

Brenda rolls the number cube 12 times and gets a 3 five times, what is the probability of getting a 3 on the next roll

Answer 1

41.67% probability of getting a 3 on the next roll

Explanation:

We use the experimental probability to solve this question, which is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

3 on the cube 5 times, so
`D = 5`

Total outcomes:

12 times that the number cube is rolled, so
`T = 12`

Probability:

`P = (D)/(T) = (5)/(12) = 0.4167`

41.67% probability of getting a 3 on the next roll
