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?
Since each participant has an equal chance of receiving a coupon for each activity, the probability of receiving a coupon for sleigh rides is 1/3. To find the expected number of people who will receive a coupon for sleigh rides, we multiply the probability by the total number of participants:
1/3 x 900 = 300
Therefore, we would expect 300 people to receive a coupon for sleigh rides.
300!!!!!!!!
Yes, the expected number of people who would receive a coupon for sleigh rides is 300.
To determine the expected number of people who would receive a coupon for sleigh rides, we need to consider that each winter activity has an equal chance of being selected.
Since there are three winter activities (skiing, snow tubing, and sleigh rides), and each activity has an equal chance, the probability of receiving a sleigh ride coupon is 1/3.
To find the expected number of people who would receive a coupon for sleigh rides, we multiply the probability by the total number of participants:
Expected number of people receiving a sleigh ride coupon = Probability of receiving a sleigh ride coupon * Total number of participants
Probability of receiving a sleigh ride coupon = 1/3
Total number of participants = 900
Expected number of people receiving a sleigh ride coupon = (1/3) * 900
Calculating:
Expected number of people receiving a sleigh ride coupon = 900/3
Expected number of people receiving a sleigh ride coupon = 300
Therefore, it is expected that 300 people would receive a coupon for sleigh rides.
