Phoebe designs bow ties for a local boutique store. The store manager counted the ties currently on display, tracking them by material and shape. The probability that a bow tie is made of cotton is 0.2, the probability that it is shaped like a butterfly is 0.7 and the probability that it is made of cotton and is shaped like a butterfly is 0.1. What is the probability that a randomly chosen bow tie is made of cotton or is shaped like a butterfly?
