If \( E \) be any event and \( E^{\prime} \) be the complement of event
\( \mathrm{P} \) \( E \) then which of the following is correct

W
(1) \( P(E)+p\left(E^{\prime}\right)=0 \) (2) \( \quad P(E)+p\left(E^{\prime}\right)1 \)
(3) \( \quad P(E)+p\left(E^{\prime}\right)1 \) (4) \( \quad P(E)+p\left(E^{\prime}\right)=1 \)
