GCSE Maths Practice: two-way-tables

Question 1 of 10

Calculate probability of a student taking French or Spanish.

›

\( \begin{array}{l}\textbf{In a class of 50 students, 30 take French, 25 take} \\ \textbf{Spanish, and 10 take both. What is the probability} \\ \textbf{that a student takes either French or Spanish?}\end{array} \)

Choose one option:

\( \frac{45}{50} \) \( \frac{40}{50} \) \( \frac{30}{50} \)

Add the counts, subtract overlap, divide by total students.

Use inclusion-exclusion to avoid double-counting students in both subjects.
