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)

To find out how many people would be expected to receive a coupon for sleigh rides, we need to determine the probability of receiving a sleigh ride coupon and then multiply it by the total number of participants.
Since participants have an equal chance of receiving each type of coupon, the probability of receiving a sleigh ride coupon is 1/3.
Therefore, the expected number of people to receive a sleigh ride coupon is:
(1/3) * 900 = 300
So, 300 people would be expected to receive a coupon for sleigh rides.
To determine how many people would be expected to receive a coupon for sleigh rides, we need to find the proportion of people who would receive each type of coupon.
Since there are three types of coupons and each participant has an equal chance of receiving each type, we can divide the total number of participants by the number of coupon types to find the expected number of people receiving each type of coupon.
First, let's find the proportion of people receiving a sleigh ride coupon. Since there are three types of coupons, each type will have an equal chance of being received by a participant.
So the proportion for sleigh rides would be: 1/3.
Next, we multiply this proportion by the total number of participants (900) to find the number of people expected to receive a sleigh ride coupon:
1/3 * 900 = 300
Therefore, it is expected that 300 people would receive a coupon for sleigh rides.
