GCSE Maths Practice: relative-frequency

Question 11 of 11

Compare relative frequencies to find the most consistent spinner.

‹

\( \begin{array}{l}\text{Three spinners are tested to see how often they} \\ \text{land on red. Spinner A: 60/120, Spinner B: 55/100,} \\ \text{Spinner C: 45/90. Which spinner gives the most} \\ \text{consistent results with a probability of 1/2?}\end{array} \)

Choose one option:

Compute decimal for each spinner and compare to 0.5.

Relative frequency closest to theoretical probability indicates consistency.
