Afitness center runs a contest for customers who enroll in its annual membership plan. the customers are allowed to draw a coupon from a jar that contains 20 coupons for 1 month of extended membership, 10 coupons for 1.5 months of extended membership, and 5 coupons for 2 months of extended membership. assuming a month has 30 days, if the expected value of extended membership (in days) on the first draw is given by the expression a + b + c, identify the correct numerical expressions for a, b, and c.

1. 20/35(30)=17.142

2. 5/35(60)=17.142

3. 10/35(60)=17.142

A = 24 , B = 12.85, C = 8.57

Step-by-step explanation:

Since we have given that

Number of coupons for 1 month = 20

Number of coupons extended for 1.5 months = 10

Number of coupons extended for 2 months = 5

Total number of coupons is given by

1 month = 30 days

So, Expected value of extended membership = A+B+C

Here, A is given by

B is given by

C is given by

So, The expected value of extended membership is given by

Hence, A = 24 , B = 12.85, C = 8.57
