Interpretation of P(A and B|C)

  1. Hello everybody!

    Should I interpret the expression P(A and B|C) as P((A and B)|C) or as P(A and (B|C))?

    Or the last expression has no meaning because P(B|C) is a ratio and I can't make an intersection with a ratio?

    I interpet it as the first. And you're right, the second expression doesn't make much sense...
  4. Thank you very much!
