When a softball player gets a hit, it can be a single, double, triple, or home run. When Josephine is at bat, the probability that 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?
A single and a double are separate possible outcomes, so add their probabilities: 15% + 5% = 20%. Therefore, the probability that Josephine hits a single or a double is 20 percent.
