4. A Canadian cell phone manufacturer buys processors from a German supplier. The company's treasurer thinks that there is probability 0.43 that the Canadian dollar will fall in value against the Euro in the next month. The treasurer also believes that if the Canadian dollar falls, there is probability 0.77 that the supplier will demand renegotiation of the contract. If the Canadian dollar does not fall, there is a probability 0.31 that the supplier will demand renegotiation. (a) Draw a tree diagram to illustrate this scenario. Properly label the prob- abilities on each branch and show any necessary calculations. (b) What has the treasurer assigned to the event that the Canadian dollar falls and the supplier demands renegotiation? (c) What total probability has the treasurer assigned to the event that the German supplier demands renegotiation? 4. A Canadian cell phone manufacturer buys processors from a German supplier.
