A construction firm bids on two different contracts. Let E1 be the event that the bid on the first contract is successful, and define E2 analogously for the second contract. Suppose that P(E1) = 0.6 and P(E2) = 0.3 and that E1 and E2 are independent events. (a) Calculate the probability that both bids are successful (the probability of the event E1 and E2). (b) Calculate the probability that neither bid is successful (the probability of the event (not E1)...

Exercise 3 (8 marks) Select a Canadian household at random, and let Abe the event that the selected household is prosperous (income exceeds $85, 000) and B the event that the household is educated (completed college). According to the Census Bureau, P(A)=0.125, P(B)=0.237, and the probability that a household is both prosperous and educated is PIA and B)=0.077. a) What is the probability that the household selected is either prosperous or educated? b) Draw a Venn diagram that shows {A...

An oil exploration company currently has two active projects, one in Asia and the other in Europe. Let A be the event that the Asian project is successful and B be the event that the European project is successful. Suppose that A and B are independent events with P(A)-0.9 and P(B) 0.s (a) If the Asian project is not successful, what is the probability that the European project is also not successful? Explain your reasoning. Since the events are independent,...
