Step 1. Given information.

The given statement is:

E is an event and $P (n o t E) = 0.4$ .

Step 2. Find PE.

The event [not A], i.e. the event in which A does not happen, is the complement of any event A. Events A and [not A] are mutually exclusive as well as exhaustive.

Therefore,

$P (E) = 1 - P (n o t E) P (E) = 1 - 0.4 = 0.6$
