Short Answer

Expert verified

The probability is0.55

Step by step solution

01

Step 1. Given Information 

The given data isP(A)=0.25,P(B)=0.45,P(A鈭�B)=0.15

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)=0.25+0.45-0.15=0.55
