probability

[divyataro]

At a certain car dealership, the 40 vehicles equipped with air conditioning represent 80% of all cars available
for sale. Among all the cars, there are 15 convertibles, 14 of which are equipped with an air-conditioning
system. If a customer is willing to purchase either a convertible or a car equipped with air conditioning, what
is the probability that a randomly selected vehicle will fit customer specifications?


can any one solve this please

My intution says A=40. B=15. AandB= 14

Therefore from set theory A or B = 40 + 15 -14 = 41

Total cars available is 50, as 40 is 80%. Therefore 41/50 = 82% probability.
