Problem 7RE
Budget Rental Cars Cheap Rentals has nothing but budget cars for rental. The probability that a car has air conditioning is 0.5, and the probability that a car has a CD player is 0.37. The probability that a car has both air conditioning and a CD player is 0.06. What is the probability that a randomly selected car has neither air conditioning nor a CD player? (4–2)
ANSWER:
Solution:
Step 1 of 2:
Given,
The P(car has air conditioning) = P(A)
= 0.5
P(car has a CD player) = P(B)
= 0.37.
P(car has both air conditioning and CD player) =P(AB)
= 0.06
The claim is to find the probability that a randomly selected car has neither air conditioning nor a CD player.
