Question

A ) 2.3

B ) 300

C ) 450

D ) 600

Answer 1

Since there are three winter activities (skiing, snow tubing, and sleigh rides), and participants have an equal chance of receiving each type of coupon, the probability of receiving a coupon for sleigh rides is:

\[ \frac{1}{3} \]

To find the expected number of people who would receive a coupon for sleigh rides, we multiply the total number of participants by the probability of receiving that coupon:

\[ \text{Expected number of sleigh ride coupons} = 900 \times \frac{1}{3} = 300 \]

Therefore, the expected number of people who would receive a coupon for sleigh rides is:

B) 300
