Question
Which of the following cannot be the probability of an event?
- `3/5`
- 2.7
- 43%
- – 0.6
- – 3.2
- 0.35
Solution
The probability of an event lies between '0' and '1' i.e. 0 ≤ P(E) ≤ 1.
i. `3/5 = 0.6`
∵ 0 ≤ 0.6 ≤ 1
Hence, it can be the probability of an event.
ii. 2.7
∵ 0 ≤ 1 ≤ 2.7
Hence, it cannot be the probability of an event.
iii. `43% = 43/100 = 0.43`
0 ≤ 0.43 ≤ 1
Hence, it can be the probability of an event.
iv. – 0.6
– 0.6 ≤ 0 ≤ 1
Hence, it cannot be the probability of an event.
v. – 3.2
– 3.2 ≤ 0 ≤ 1
Hence, it cannot be the probability of an event.
vi. 0.35
0 ≤ 0.35 ≤ 1
Hence, it can be the probability of an event.
