What is the formula for conditional probability P(A|B)?

A. P(A∩B) / P(B)

Step 1: Identify conditional probability. Step 2: When B is assumed to have occurred, B becomes the sample space and P(A|B)=P(A∩B)/P(B). Step 3: Memory tip: The event after the condition bar goes in the denominator.

Step 1: अवधारणा conditional probability है। Step 2: जब B हो चुका माना जाता है, तो sample space B बनता है और P(A|B)=P(A∩B)/P(B)। Step 3: Memory tip: condition जिस पर है, वही denominator में आता है।
