Answer:
Note: The full question is attached as picture below
a. Let X is denoted as company’s monthly demand, P(X=x) is denoted as the probability of the company’s monthly demand.
The expected value is obtained below:
E(X) = (300*0.20) + (400*0.30) + (500*0.35) + (600*0.15)
E(X) = 60+120+175+90
E(X) = 445
b. The expected value of the monthly demand is 445. The each unit demands the revenue to generate is $70 and their cost is $50.
The gain/loss of the company = (300*(70−50)) - (145*50)
The gain/loss of the company = (300*20) - (145*50)
The gain/loss of the company = 6,000 - 7,250
The gain/loss of the company =−$1,250(Loss)
