Question

If $E$ is an event, then $P\left(E\right)+P(notE)=0$.

• A. True
• B. False

Answer 1

The correct option is B False

The sum total of probability of happening of any event and the probability of not happening of any event is $1$. For example- If we toss a coin either we get head or tail. The probability of getting a head is $\frac{1}{2}$ and the probability of not getting a head or getting a tail is $\frac{1}{2}$. Therefore, the sum of probability of getting a head and probability of not getting a head is $1$.

Hence, the given statement is false.
