Question

A lucky customer at "Used Car Charlie's Lot" will get to randomly select one key from a barrel of keys. The barrel contains the keys to all of the cars on Charlie's lot. The inventory lists 80 cars, of which: 38 are foreign models 50 compact models 22 foreign compact models What is the probability that the lucky customer will win a nonforeign compact car?

Answer 1

Answer: Our required probability is $\dfrac{29}{40}$

Step-by-step 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

$\dfrac{22}{80}=\dfrac{11}{40}$

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

$1-\dfrac{11}{40}\\\\=\dfrac{40-11}{40}\\\\=\dfrac{29}{40}$

Hence, our required probability is $\dfrac{29}{40}$

Answer 2

Answer:0.625

Step-by-step explanation:

Given

A lucky customer will get to randomly select a key among 80 cars

There are 38 foreign models

50 compact models

22 Foreign compact models

Probability that the lucky customer will win a non foreign compact car$=\frac{no.\ of\ non\ foreign\ compact\ car}{Total\ no\ of\ car}$

$=\frac{50}{80}$
