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)

Answer 1

There are three equally likely coupons, so probability of a sleigh-ride coupon = 1/3. Expected number = 900 × (1/3) = 300.
