IfP(B)=0.30,P(A∪B)=0.65andP(A∩B)=0.15,findP(A)

Short Answer

Expert verified

The probability is0.50

Step by step solution

01

Step 1. Given Information  

The given data isP(B)=0.30,P(A∪B)=0.65andP(A∩B)=0.15

02

Step 2. Calculation

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

P(A∪B)=P(A)+P(B)-P(A∩B)0.65=P(A)+0.30-0.15P(A)=0.65+0.15-0.30P(A)=0.50
