After growing tired of squinting while driving, Bella went shopping for a pair of sunglasses. She tried on glasses with different frames and lenses. The probability that a pair of sunglasses has wayfarer frames is 0.6, the probability that it has regular lenses is 0.18, and the probability that it has wayfarer frames and regular lenses is 0.07. What is the probability that a randomly chosen pair of sunglasses has wayfarer frames or regular lenses?
