Question

As part of a promotion, people who participate in a survey are sent a free
coupon for one of three winter activities: skiing, snow tubing, or sleigh rides.
Participants have an equal chance of receiving each type of coupon. If 900
people participate, how many would be expected to receive a coupon for sleigh
rides? (1 point)

300

600

2
3

450

Answer 1

Each person has a 1/3 chance of a sleigh-ride coupon, so expected number = 900 × 1/3 = 300.
