Answer 1

The experimental probability of the arrow stopping over Section 3 is 2/5 or 0.4. This is calculated by dividing the number of times Section 3 was hit (32) by the total number of spins (80).

Step-by-step explanation:

The question deals with the experimental probability of an event occurring when a spinner is used. The experimental probability is calculated by dividing the number of times an event occurs by the total number of trials. In this case, the spinner landed on Section 3 a total of 32 times out of 80 spins.

To find the experimental probability of the arrow stopping over Section 3, you would use the formula:

Experimental Probability = (Number of times an event occurs) / (Total number of trials)

So, the experimental probability of hitting Section 3 is:

Experimental Probability of Section 3 = 32 / 80

This can be simplified to:

Experimental Probability of Section 3 = 2 / 5 or 0.4
