After growing tired of squinting while driving, Desmond went shopping for a pair of sunglasses. He tried on glasses with different frames and lenses. What is the probability that a randomly selected pair of sunglasses has cat eye frames and does not have regular lenses? Simplify any fractions.

Answer 1

The probability that a randomly selected pair of sunglasses has cat eye frames and does not have regular lenses is 1/4.

This is because there are 2 pairs of sunglasses with cat eye frames and polarized lenses, and there are a total of 8 pairs of sunglasses without regular lenses. So the probability is 2/8 = 1/4.
