By examining the past driving records of city driers, an insurance company has determined the following (empirical) probabilities: If a city driver is selected at random, what is the probability that He or she drives less than 10,000 miles per year or has an accident? He or she drives 10,000 or more miles per year and has no accidents? Use the (empirical) probabilities in Problem 73 10 find the probability that a city driver selected at random: Drives more than 15,000 miles per year or has an accident Drives 15,000 or fewer miles per year and has an accident control.

Solution

(A) He or she drives less than 10000 miles per year or has an accident

P(A) = 0.05 + 0.15 + 0.1 + 0.15 = 0.45

(B) He or she drives 10000 or more miles per year and has no accidents

P(B) = 0.1 + 0.15 + 0.2 + 0.35 + 0.15 = 0.95

Q74)

a) Drives more than 15000 miles per year or has an accident

P(C) = 0.15 + 0.35 + 0.05 + 0.1 = 0.65

b) Drives 15000 or fewer miles per year and has an accident

P(D) = 0.1+0.05 = 0.15
