Question 6 of 10

Calculate probability a person likes tea or coffee.

\( \begin{array}{l}\textbf{In a group of 60 people, 35 like tea, 30 like coffee,} \\ \textbf{and 20 like both. What is the probability that a person} \\ \textbf{likes tea or coffee?}\end{array} \)

Choose one option:

Add counts, subtract overlap, divide by total students.

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