Chapter 5: Q 5.79. (page 216)

Suppose that A and B are mutually exclusive events such that P(A)=0.25andP(B)=0.40DetermineP(AorB).

Short Answer

Expert verified

As a result, P(AandB)has a value of0.65

Step by step solution

01

Step 1. Given information. 

P(A)=0.25P(B)=0.4

02

Step 2. P(A and B) is zero for mutually exclusive events.

The following formula is used to determine P(AandB):

P(AorB)=P(A)+P(B)0.25+0.4=0.65

As a result, P(AandB)has a value of0.65
