Suppose that a manufacturing process is such that the probability of a card being correctlypopulated with microchips is 0.85. For each correctly populated card that a retailer buys from themanufacturer, the retailer makes a profit of 50 rand while for each incorrectly populated card, theretailer makes a loss of 30 rand.Miss Kekana is a retailer and she has decided to buy 22 cards from the manufacturer? The mean ofthe amount of money that Miss Kekana will make is

p(correctly populated)=0.85 ∴p(incorrectly populated)=0.15if correctly populated : profit 50 rand…

Answered: Suppose that a manufacturing process is…
