Question:

6.11 Profit and the weather From past experience, a wheat farmer living in Manitoba, Canada, finds that his annual profit (in Canadian dollars) is $80,000 if the summer weather is typical, $50,000 if the weather is unusually dry, and $20,000 if there is a severe storm that destroys much of his crop. Weather bureau records indicate that the probability is 0.70 of typical weather, 0.20 of unusually dry weather, and 0.10 of a severe storm. Let X denote the farmer’s profit next year.

a. Construct a table with the probability distribution of X.

b. What is the probability that the profit is $50,000 or less?

c. Find the mean of the probability distribution of X.

Interpret.

d. Suppose the farmer buys insurance for $3000 that pays him $20,000 in the event of a severe storm that destroys much of the crop and pays nothing otherwise.

Find the probability distribution of his profit.

Find the mean and summarize the effect of buying this insurance.
