Question

A spinner with 9 equal sections labeled with the letters A, A, B, B, B, C, C, C, and D is spun 198 times. Which of
the following correctly predicts how many times the spinner will land on the letter B? (1 point)

22 times

44 times

66 times

198 times

Answer 1

There are 3 B sections out of 9, so the probability of B on one spin is 3/9 = 1/3. Expected number of B's in 198 spins = 198 × 1/3 = 66.
