Answer:

"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.

Step-by-step explanation:

The actual probability of the given scenario will be:

⇒  (1-\frac{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.
