Question

If the spinner is spun 100 times, how many times would you expect it to land in region E? Explain.

Answer 1

The probability that the spinner will land on Region E is:

Count of pieces in Region E 4 4
----------------------------------------- = ------------------- = ---------- = 1/3, or 0.333...
Total # of pieces in all regions 2+2+3+1+4 12

Thus in 100 spins, the spinner will land in Region E approx. (1/3)(100) times, or
33 times.
