Question

Rory was with some friends outside an ice cream parlor. He noticed that one out of every four people bought a vanilla cone. He wants to know the estimated probability that five randomly picked people entering the shop will not buy vanilla cones. How could you design a simulation of the scenario?

Answer 1

Spin a spinner with four equal sections five times. On the spinner, one section represents vanilla and three sections represent other flavors.

Answer 2

"Spin the spinner 5 times with 4 equal segments. One of the segment represents vanilla on either the spinner as well as three parts reflect certain flavors" would be the right answer.

Explanation:

The actual probability of the given scenario will be:

⇒
`(1-(1)/(4))^5`

⇒
`(1-0.25)^5`

⇒
`(0.75)^5`

On solving the power, we get

⇒
`(0.237304)`

Now on multiplying the above value in 100, we get

⇒
`23.73`%

Approximately 23.73% chance vanilla was not chosen by either of the five. So that the above is the right answer.
