Show answer & explanation

Correct answer: D

Each car's color is independent and can be red or blue with equal probability 1/2.

For five cars, the probability that they are all red is (1/2)^5 = 1/32.

Similarly, the probability that they are all blue is also (1/2)^5 = 1/32.

The events "all red" and "all blue" are mutually exclusive, so the probability that all five cars are the same color is 1/32 + 1/32 = 2/32 = 1/16.

Therefore, the probability that five consecutive cars are of the same color is 1/16.
