Question

When a softball player gets a hit, it can be a single, double, triple, or home run. When Josephine is at bat, the protectity

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?

Answer 1

The probability of hitting a single or a double is 1/5 or 20% or 20/100 or 0.2

Explanation:

In probability, whenever we are to answer an ‘or’ question, we add up the probabilities involved.

The probability of hitting a single is 15%, that is same as 15/100 or just simply 0.15

The probability of hitting a double is 5%, that is simply 5/100 or just simply 0.05

The probability of hitting a single or a double = Probability of hitting a single + Probability of hitting a double = 0.15 + 0.05 = 0.20 or 20/100 or 1/5
