Hi Guys!!! I'm wondering what the difference is between composed probabilities and total probabilities. Can someone enlighten me?

Composed probability is not a standard term. Where did you get it?

I assume that a composed probability is simply a product. For example, P(A) = P(B)P(C) if it is known that event A occurs only if the mutually independent events B and C both occur. If, on the other hand, B and C are mutually exclusive events, and if the occurrence of either of them implies that event A occurs, one would have P(A) = P(B) + P(C), which gives P(A) as a total probability.
