Question

A number cube is rolled 20 times and lands on 1 two times and on 5 four times.Find the theoretical probability of 5?

Answer 1

The theoretical probability of 5 is 0.25

Explanation:

A number cube is rolled 20 times.

Lands 5 four times.

We need to find the probability of 5.

Formula: Probability =
`\frac{\text{Favorable outcomes}}{\text{Total outcomes}}`

Number of outcomes = 5

Total number of rolled = 20

Probability ( Number 5)
`=(5)/(20)=0.25`

Hence, The theoretical probability of 5 is 0.25
