Question

If $P\left(E\right)$ denotes the probability of an event $E$, then $E$ is called certain event if:

• A. $P\left(E\right)=0$
• B. $P\left(E\right)=1$
• C. $P\left(E\right)$ is either $0$ or $1$
• D. $P\left(E\right)=1/2$

Answer 1

The correct option is B $P\left(E\right)=1$

Given $E$ is a certain event and $P\left(E\right)$ denotes the probability of the event $E$.

We know that, "An event is said to be a Certain Event if there is an absolute surety on the chance of its occurrence." The probability of certain event is said to be $1$.

Therefore, $P\left(E\right)=1$.
