Answer: 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

20+10+5=35

1 month = 30 days

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

Here, A is given by

\dfrac{20}{35}\times 30\\\\=24

B is given by

\dfrac{10}{35}\times 1.5\times 30\\\\=12.85

C is given by

\dfrac{5}{35}\times 2\times 30\\\\=8.571

So, The expected value of extended membership is given by

A+B+C=24+12.85+8.57=45.42

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