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

Answer 1

Since participants have an equal chance of receiving each type of coupon, the probability of receiving a coupon for sleigh rides is 1/3.

Therefore, the expected number of participants who would receive a coupon for sleigh rides can be calculated as:

Expected number = Total number of participants * Probability of receiving a coupon for sleigh rides
Expected number = 900 * 1/3
Expected number = 900/3
Expected number = 300

Therefore, it is expected that 300 participants would receive a coupon for sleigh rides.
