If P(A)=0.6, P(B)=0.5 and P(A∪B)=0.8, what is P(A∩B)?
यदि P(A)=0.6, P(B)=0.5 और P(A∪B)=0.8 है, तो P(A∩B) क्या है?
Show answer and explanation
Correct Answer
C. 0.3
ExplanationStep 1: Identify addition theorem. Step 2: P(A∪B)=P(A)+P(B)-P(A∩B), so 0.8=0.6+0.5-x and x=0.3. Step 3: Exam tip: In union formula, intersection is subtracted.
Step 1: अवधारणा addition theorem है। Step 2: P(A∪B)=P(A)+P(B)-P(A∩B), इसलिए 0.8=0.6+0.5-x और x=0.3। Step 3: Exam note: union formula में intersection subtract होता है।
