Question

Which of the following cannot be the probability of an event?

1. `3/5`
2. 2.7
3. 43%
4. – 0.6
5. – 3.2
6. 0.35

Answer 1

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.
