Question

A construction company is considering submitting bids for two contracts. It will cost the company \$10{,}000$10,000dollar sign, 10, comma, 000 to prepare and submit the bids, and if won, each bid would produce \$50{,}000$50,000dollar sign, 50, comma, 000 of income to the company. The company estimates that it has a 10\%10%10, percent chance of winning any given bid.
Here is the probability distribution of X=X=X, equals the number of bids the company wins, and M=M=M, equals the amount of money the company profits from the bids.

Calculate the mean of MMM.

Answer 1

Answer:

0 dollars

=E(M)

=μ  

M

​  

=−$10,000(0.81)+$40,000(0.18)+$90,000(0.01)

=−8,100+7,200+900

=0
