You have, on the bottom the number of cars and on the left the corresponding probability.

The probability of having 4 cars is 0.05; the probability of having 5 cars is 0.05 again.

Therefore, the probability of having more than 3 cars is P(4) + P(5) = 0.10 which corresponds to 10%.

The correct answer is 0.10
