MCQ
Which of the following can not be the probability an event ?
- ✓$1.5$
- B$\frac{3}{5}$
- C$25\%$
- D$0.3$
✓
Answer
Correct option: A.
$1.5$
$0\leq\text{Probability of event E}\leq1$
Probability of an event $(E)$ is always greater than or equal to $0$.
Also, it is always less than or equal to one.
This implies that the probability of an event cannot be negative or greater than $1.$
Therefore, out of these alternatives, $1.5$ cannot be a probability of an event.
Hence $,(A)$.
