    Request for help on probability.




    Hi All,
    I need your help to solve this question. I am preparing for exam and trying to solve this question.

    A ball is selected from a box containing 2 black balls, numbered 1 and 2, and 2 white balls, numbered 3 and 4. The number and color of the ball is noted, so the sample is {(1,b), (2,b), (3,w),(4,w)}.
    Assuming that four outcomes are equally likely, find P[A|B] and P[A|C], where A, B and C are following events:
    A= {(1,b), (2,b)}, "black ball selected",
    B= {(2,b), (4,w)}, "even-numbered ball selected" and
    C= {(3,w), (4,w)}, "number of ball is greater than 2".

    You could not even start? What have you learned conditional probability?
