(a)
(i) Write down the probability of the spinner landing on 2. [1]
(ii) Write down the probability of the spinner not landing on 2. [1]
(b) Write down an outcome for the spinner that has a probability of 0. [1]
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| (i) \(\frac{1}{5}\) or 0.2 or 20% | 1 | Accept an equivalent fraction or “one fifth” but not ratio e.g. 1 : 5 or 1 in 5 or words e.g. unlikely Ignore attempts to cancel or change form once correct answer seen | |
| (ii) \(\frac{4}{5}\) or 0.8 or 80% | 1FT | FT 1 – their (a)(i) | Accept equivalent fraction or “four fifths” but not ratio e.g. 4 : 5 or 4 in 5 or words e.g. likely Ignore attempts to cancel or change form once correct answer seen |

| An example using the spinner that has a probability of 0 e.g. [landing/spinning/getting a] 6 | 1 | Condone: “Getting a number that is not on the spinner” oe Do not accept descriptions of events other than numbers e.g. it never stops spinning “There’s no 0 on the spinner” scores 0 “Getting a 0” scores 1 Condone “dice” for “spinner” | |
