Webprobabilities for when the joint probability distribution is given in factored form and the sets of variables involved in the factors form a hypertree. Previous expositions of such local computation have emphasized conditional probability. We believe this emphasis is misplaced. What is essential to local computation is a factorization. WebI have a conditional probability P(C A,B) which I custom-design as a function. The function is a probability distribution of C given each (a,b) as parameter: $ P(C=c A=a,B=b) \sim \mbox{Beta distribution of C with mean} = a b $. The variance of distribution C would be the average of the variances of distributions A and B.

"The marginal probability is the probability of a single event occurring, independent of other events. A conditional probability, on the other hand, is the probability that an event occurs given that another specific event has already occurred. This means that the calculation for one variable is dependent on another variable. The conditional distribution of a variable given another variable is the joint distribution of both va… " - Marginalize conditional probability
