P(A)=5/7 and P(A∩B)=1/7. What is P(B|A)?
P(A)=5/7 और P(A∩B)=1/7 है। P(B|A) क्या है?
Show answer and explanation
Correct Answer
D. 1 / 5
ExplanationStep 1: Identify the concept: conditional probability. Step 2: P(B|A)=P(A∩B)/P(A). Substitution gives 1/5. Step 3: Exam tip: The conditioning event goes in the denominator.
Step 1: अवधारणा conditional probability है। Step 2: P(B|A)=P(A∩B)/P(A)। Values रखने पर 1/5। Step 3: याद रखें: Condition वाली event denominator में रखें।
