Answer: Our required probability is
(29)/(40)

Explanation:

Since we have given that

Number of foreign models = 38

Number of compact models = 50

Number of foreign compact model = 22

Total number of cars = 80

Probability that consumer will win foreign compact models is given by


(22)/(80)=(11)/(40)

so, Probability that consumer will win non foreign compact models is given by


1-(11)/(40)\\\\=(40-11)/(40)\\\\=(29)/(40)

Hence, our required probability is
(29)/(40)
