he ratio of hybrid cars to gasoline-powered cars in the parking lot of a building is 3:11. If there are 280 cars in the lot and one is selected at random to get the reserved spot, what is the probability it will be a hybrid? show work

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%.
