#1. A certain airplane has two independent alternators to provide electrical power.

The probability that a given alternator will fail on a 1-hour flight is .02.

What is the probability that

(a) both will fail?

(b) Neither will fail?

(c) One or the other will fail? Show all steps carefully.

#2. The probability is 1 in 4,000,000 that a single auto trip in the United States will result in a fatality. Over a lifetime, an average U.S. driver takes 50,000 trips.

(a) What is the probability of a fatal accident over a lifetime? Explain your reasoning carefully. Hint: Assume independent events. Why might the assumption of independence be violated?

(b) Why might a driver be tempted not to use a seat belt “just on this trip”?
