Chapter 5: Q 11. (page 246)

E is an event and P(notE)=0.4FindP(E).

Short Answer

Expert verified

The probability isP(E)=0.6.

Step by step solution

01

Step 1. Given information.

The given statement is:

E is an event andPnotE=0.4.

02

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,

PE=1-PnotEPE=1-0.4=0.6
