Homework Help: Joint Conditional Probability

  1. Apr 2, 2012 #1
    1. The problem statement, all variables and given/known data
    I have access to P(x|A) and P(y|A), P(x), P(y) and P(A), in addition to the knowledge that x and y are independent variables. I am interested in finding P(A|x,y).

    3. The attempt at a solution

    I think that
    P(A|x,y) = P(x,y|A) * P(A) / P(x,y) = P(x,y|A) * P(A) / (P(x)*P(y))

    I am not particularly good at probability and am dealing with probabilities after considerable time, would like to know if i am doing anything wrong or is my answer correct.
