Worked practice questions
If the probability of an event is 0.3, the probability of it not happening is:
- 0
- 0.3
- 0.7
- 1.3
Show answer and solution
Correct answer: C. 0.7
P(not E) = 1 − 0.3 = 0.7.
The probability of getting a number greater than 6 in a single roll of a die is:
- 0
- 1
- 6
- 1/6
Show answer and solution
Correct answer: A. 0
A die shows only 1–6, so 'greater than 6' is impossible → 0.
