Hints

Open one hint at a time and try again before the next.

Hint 1

A sure event contains every possible outcome.

Hint 2

Check whether each event includes all of 1, 2, 3, 4, 5, 6.

Step-by-step solution

Each step shows the marks it earns, as an examiner would award them. Checked by an independent re-solve from the question paper.

  1. Every outcome of a die (1 to 6) is a natural number less than 7, so this event always happens.

  2. 'Between 1 and 6' leaves out 1 and 6, and the odd or even events leave out half the outcomes. So the sure event is option (D).

    1 mark

Answer: Option (D)

Where the marks are

  • Identifies the event that contains all six outcomes (1 mark)
