mark noticed that his bus is late to school 5% of the time. he wants to design a spinner he can use to simulate the situation and determine the probability that the bus will be late three times next week. how should mark divide his spinner to best simulate the situation? 2 equal - sized sections 5 equal - sized sections 15 equal - sized sections 20 equal - sized sections

Answer

Explanation:

Step1: Recall probability concept

The bus is late 5% of the time, which is $\frac{5}{100}=\frac{1}{20}$ in fraction form.

Step2: Match with spinner - sections

To simulate the situation with a spinner, we need to divide the spinner into sections such that the probability of landing on the "late - bus" section is $\frac{1}{20}$. So, we should divide the spinner into 20 equal - sized sections.

Answer:

20 equal - sized sections
