Question

The ratio of hybrid cars to gasoline-powered cars in the parking lot of a local office building is 3:11. if there are 280 cars in the lot and one is to be selected at random to get the reserved parking space nearest the building, find the probability the car selected is a hybrid. express your answer as a fraction.

Answer 1

The probability that it will be a hybrid is 21.4%.

Probability is the ratio of number of occurrences to total number of possible occurrences.

Given a total number of 280 cars. The number of hybrid cars is gotten by using the ratio.

Number of hybrid cars = (3/14) * 280 = 60 cars

Probability of picking a hybrid car = Number of hybrid car/total number of cars = 60 cars / 280 cars = 21.4%

Therefore the probability that it will be a hybrid is 21.4%.
