A wilderness retail store asked a consulting company to do an analysis of their hiking shoe customers. The consulting company gathered data from each customer that purchased hiking shoes, and recorded the shoe brand and the customer's level of happiness. The probability that a customer purchased a Step-To-It shoe is 0.4, the probability that a customer is very pleased is 0.3 and the probability that a customer purchased a Step-To-It shoe and is very pleased is 0.1. What is the probability that a randomly chosen customer purchased a Step-To-It shoe or is very pleased?
