a) The probability that the firm will get a taxi with bad tires is:

P=0.1×0.2+0.12×0.2+0.04×0.6=0.068P = 0.1×0.2 + 0.12×0.2 + 0.04×0.6 = 0.068 or 6.8%.

b) The probability that a taxi with bad tires rented by the firm came from agency A using the formula for conditional probability is:

P=0.1×0.2/0.068=0.294P = 0.1×0.2/0.068 = 0.294 or 29.4%.
