Q3 of 54 Page 315

If P (E)=0.05. What is the probability of ‘notE’?

If a probability of an event to be happen is P. Then event not to happen will (1 – P).

Here, probability of event ‘E’ is given as –


⇒ P(E)=0.05


⇒ P(not E)= P(E̅ ) = 1 – P(E)


⇒ P(E̅ )= 1 – 0.05


⇒ P(E̅ )=0.95


∴ probability of ‘notE’ = 0.95
