GCSE Maths Practice: relative-frequency

Question 3 of 10

This question calculates relative frequency from repeated draws.

‹ ›

\( \begin{array}{l}\text{A bag contains 5 red and 3 blue marbles.} \\ \text{The bag is shaken 40 times, and a red marble is drawn 20 times.} \\ \text{What is the relative frequency of drawing a red marble?}\end{array} \)

Choose one option:

\( \frac{20}{40} \) \( \frac{1}{2} \) \( \frac{5}{8} \)

Compute fraction of red occurrences over total trials.

Relative frequency = red outcomes ÷ total draws.
