Answer: Around 50 times.

Step-by-step 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
