Question

What if the probability is greater than $1$?

Answer 1

Probability Theory:

Probability is a measure of the likelihood of an event to occur. Probability is a number or fraction between $0$ and $1$.

By the definition of probability, for all the events in the event space, the probability is less than or equal to $1$.

This means the probability of an event $E$ is: $0\le P\left(E\right)\le 1$

Hence, Probability can not be greater than $1$.
