To determine Obtain the expected profit. Explanation In this scenario, X denotes the number of cartons sold and Y denotes profit. In this context, the retail price per carton milk is $1.65. The credit amount received from the distributor is 0.9 ( = 1.20 × 3 4 ) . For unsold milk, the grocer receives a three-fourth of the credit from the wholesale price for all carton is 0.9 ( 5 − X ) − 6 . The profit, Y will be as follows: Y = 1.65 + 0.90 ( 5 − X ) − 6 = 0.75 X − 1.50 Theorem 4.5 states that if a and b are constants, then E ( a X + b ) = a E ( X ) + b . The expected profit is obtained as given below: E ( Y ) = E ( 0.75 X − 1.50 ) = 0.75 E ( X ) − 1.50 For E ( X ) , μ = E ( X ) = ∑ x f ( x ) = { ( 0 ) P ( X = 0 ) + ( 1 ) P ( X = 1
