Question

If $P\left(E\right)=0.05$. what is probability of 'not E'?

• A. $0$
• B. $0.05$
• C. $0.95$
• D. $0.85$

Answer 1

The correct option is C $0.95$

Given: $P\left(E\right)=0.05$

Probability of not happening of $P\left(E^{\prime }\right)=1-P\left(E\right)$

$P\left(E^{\prime }\right)=1-0.05=0.95$
