When a softball player gets a hit, it can be a single, double, triple, or home run. When Josephine is at bat, the probability th
at she hits a single is 15 percent and the probability that she hits a double is 5 percent. What is the probability that Josephine hits a single or a double when she is at bat?
The key word here is "or". If it's an OR question, you add the probabilities together. If it says "and", you multiply them together As it is an OR question though, you add them. So: 15 + 5 = 20%
