There are a total of 14 pairs of sunglasses (3 cat eye with polarized lenses, 4 cat eye with regular lenses, 3 browline with polarized lenses, 4 browline with regular lenses).
The probability of selecting a pair of sunglasses with regular lenses and browline frames is:
4 (browline with regular lenses) / 14 (total pairs) = 2/7 = 0.2857
So, the probability is 2/7 or approximately 0.2857.
After growing tired of squinting while driving, Will went shopping for a pair of sunglasses. He tried on glasses with different frames and lenses.
Cat eye frames Browline frames
Polarized lenses 3 4
Regular lenses 3 4
What is the probability that a randomly selected pair of sunglasses has regular lenses and browline frames?
