Chapter 13: Q. 46 (page 866)

Find the probability of the indicated event if P(A)=0.25andP(B)=0.45

P(A鈭�B)ifP(A鈭�B)=0.6

Short Answer

Expert verified

The probability is0.1

Step by step solution

01

Step 1. Given Information 

The given data isP(A)=0.25,P(B)=0.45,P(A鈭�B)=0.6

02

Step 2. Calculation  

Substitute the given values in the formula to find the required value,

P(A鈭�B)=P(A)+P(B)-P(A鈭�B)P(A鈭�B)=P(A)+P(B)-P(A鈭�B)P(A鈭�B)=0.25+0.45-0.6P(A鈭�B)=0.1
