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)
Since participants have an equal chance of receiving each type of coupon, the probability of receiving a coupon for sleigh rides is 1/3.
Expected number of people receiving a coupon for sleigh rides = 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 people would receive a coupon for sleigh rides.
