  • bhanwar04, I think you are confused about the difference between joint and conditional probability. Joint probability is *and* and would be P(A&B). conditional probability is *given*. In the example, P(A'|B') is the probability of event A *given* event B. You might need to watch the previous lecture.

  • thanx for video. i have some questions. i think maths easy but what irks me is interpreting conditional and joint probability.

    Please tell me the meaning of P(AB), P(A|B),P(A'|B) keeping last example in mind.
