Final answer:
The probability of randomly selecting a car from the given sample that has either 2 doors or 4 doors is 0.77.
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
Probability = expected outcome of event/total outcome of event
According to the set diagram;
the total number of cars that has 2 doors = 14+18 = 32
the total number of cars that has 4 doors = 20+25 = 45
Probability of randomly selecting a car that has 2 doors = 32/100
Probability of randomly selecting a car that has 4 doors = 45/100
Probability that a randomly selected car from this sample had 2 doors or 4 doors = P(2 or 4) = 32/100+45/100 = 77/100
So, the probability is 0.77.
