Question 3 of 10

Calculate probability a student likes reading or writing.

\( \begin{array}{l}\textbf{In a class of 40 students, 25 like reading,} \\ \textbf{15 like writing, and 10 like both. What is the} \\ \textbf{probability that a student likes either reading or writing?}\end{array} \)

Choose one option:

Add counts, subtract overlap, divide by total students.

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