The question, in short
From a table of probabilities for four travel methods with 450 students, use the given probabilities 0.20, x, 2x and 0.26 to work out how many students travelled by car.
Summarised in our own words. Use the official paper for the exact wording and any diagrams.
Solution · 4 marks
- 10.20 + 0.26 = 0.46
- 21 − 0.46 = 0.54
- 3x + 2x = 0.54
- 43x = 0.54
- 5x = 0.18
- 62x = 0.36
- 70.36 × 450 = 162
