As part of a promotion people who participate in a survey or send a free coupon for one of three winter activity 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
Since each participant has an equal chance of receiving each type of coupon, the probability of getting a coupon for sleigh rides is 1/3.
Therefore, the expected number of people 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 = 300
Therefore, it is expected that 300 people would receive a coupon for sleigh rides.
