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 slay ride 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.
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 people who would receive a coupon for sleigh rides is calculated as follows:
Expected number = Total number of participants x Probability of receiving coupon for sleigh rides
Expected number = 900 x 1/3
Expected number = 300
Thus, we would expect 300 people to receive a coupon for sleigh rides.
