Foundation November 2019 Paper 3 Q21
21 A spinner has five equal sections.
Write a number in each section so that
the numbers are all different factors of 100
P(single-digit number) \(= \dfrac{3}{5}\)
P(multiple of 25) \(= \dfrac{1}{5}\) [3 marks]
| Answer | Mark | Comments |
|---|---|---|
| Five different factors of 100 on the spinner | B1 | 1 2 4 5 10 20 25 50 100 |
| Exactly three single digit numbers on the spinner all of which are factors of 100 | B1 | 1 2 4 5 allow repeats |
| Exactly one multiple of 25 on the spinner | B1 |
Additional guidance
| A fully correct answer will consist of a spinner with three of 1 2 4 5 and exactly one of 25 50 100 and exactly one of 10 20 | |
