What examiners said
Some candidates ignored their answer to part (a) and did not proceed correctly. Most chose to list the times the two bells rang. This work gained one mark or two marks for one or both bells. Those that chose to do two lists, rather than one timeline for both bells, were the most successful. Some appeared to get confused with what time they had got up to, so instead gave an answer of 09 30 the next...
— Examiner report, May/June 2025, 0607/11 Q14(b) (Cambridge)
Most realised the need to add 0.6 and 0.15 and as they did not set this out as a column addition, this led to the common error that 0.6 + 0.15 = 0.21. Some performed the addition correctly then omitted to subtract their answer from 1. Another common error was to think that all the probabilities totalled 40 (which was the total number of balls in the box) or 40% which led to calculations such as 40...
— Examiner report, May/June 2025, 0607/11 Q15(a) (Cambridge)
Often an incorrect answer was given without any working so the method could not be seen. This was only a single mark question but that does not mean that workings are not needed to get to the answer. Candidates needed to work out the total number of balls multiplied by the probability of getting a white ball, 40 × 0.6 = 24.
