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?
○ 3 percent
○ 10 percent
○ 20 percent
○ 75 percent

Explanation:

Step1: Identify mutually exclusive events

Hitting a single and hitting a double are mutually exclusive (a player cannot hit both at the same at-bat), so we add their probabilities.

Step2: Sum the given probabilities

Let $P(\text{single}) = 15\%$ and $P(\text{double}) = 5\%$. Calculate $P(\text{single or double}) = P(\text{single}) + P(\text{double})$
$15\% + 5\% = 20\%$

Answer:

20 percent
