GCSE Maths Practice: two-way-tables

Question 2 of 10

Calculate probability of a student liking soccer or basketball.

‹ ›

\( \begin{array}{l}\textbf{In a class of 80 students, 50 like soccer, 40} \\ \textbf{like basketball, and 30 like both. What is the} \\ \textbf{probability that a student likes either soccer or basketball?}\end{array} \)

Choose one option:

\( \frac{60}{80} \) \( \frac{50}{80} \) \( \frac{40}{80} \)

Add counts of each sport, subtract overlap, divide by total students.

Use inclusion-exclusion principle to avoid double-counting students liking both sports.
