Question 7 of 10

Calculate probability a person likes soccer or basketball.

\( \begin{array}{l}\textbf{In a set of 100 people, 70 like soccer, 50 like basketball,} \\ \textbf{and 40 like both. What is the probability that a person likes} \\ \textbf{either soccer or basketball?}\end{array} \)

Choose one option:

Add counts, subtract overlap, divide by total students.

Use inclusion-exclusion principle to avoid double-counting people who like both sports.
