Question

F.I.B:-
let E be an event.
Then P(not E) =??
​

Answer 1

Given,

E be any event.

To find,

P(not E )

Solution,

The value of  P(not E) is 1-P(E).

We can simply find the probability of not E by using the result,

P(E) + P(not E) = 1

P( not E ) = 1-P(E)

Hence, the value of P(not E) is 1-P(E).
