Hi There,
some of you may have noticed that in Formula Booklet in the same box as the Conditional Probability formula, which is P(A|B)=P(A union B)/ P(B) , there is Bayes' Theorem. It is a far more complicated formula for doing conditional probablility. Do you know if we are ever expected to use it in IB maths exams, and what makes it different from the usual conditional probability formula?
Cheers
