Question

Students are given a spinner with 5 equal sectors numbered 1-5. They are instructed to spin 50 times and record the number the arrow lands on. If there are 5 groups of students spinning, which of the following is most likely the total number of times the spinner lands in the 3 sector?

Answer 1

Answer: Around 50 times.

Explanation:

If the spinner is fair, then each number should have the same probability, that is P = 1/5 = 0.20 for each of the numbers.

Now, we know that we have 5 groups, and each group spins 50 times (so we have a total of 5*50 = 250 spins)

Then we can expect to see the number 3 around:

0.20*150 = 50
