1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution For part A I solved for P(B|JC) = P(B,JC)/P(JC) For part B I am thinking P(B|!JC, MC) = P(B, !JC, MC) / P(!JC, MC) For part C I am thinking P(JC|MC) = P(JC, MC)/P(MC) Am I on track with these equations? Especially for part c? How do I compute P(JC, MC)?
