GCSE Maths Practice: theoretical-vs-experimental-probability

Question 11 of 11

Calculate experimental probability for a spinner.

‹

\( \begin{array}{l}\text{A spinner has 6 equal sections: red, blue, green, yellow, purple, black.} \\ \text{It lands on blue 9 times in 30 spins. What is the experimental probability?}\end{array} \)

Choose one option:

\( \frac{9}{30} \) \( \frac{3}{10} \) \( \frac{1}{6} \)

Divide observed blue occurrences by total spins.

Experimental probability = blue outcomes ÷ total spins.
