In statistics, the conditional probability table (CPT) is defined for a set of discrete and mutually dependent random variables to display conditional probabilities of a single variable with respect to the others (i.e., the probability of each possible value of one variable if we know the values taken on by the other variables). For example, assume there are three random variables where each has states. Then, the conditional probability table of provides the conditional probability values – where the vertical bar means “given the values of” – for each of the K possible values of the variable and for each possible combination of values of This table has cells. In general, for variables with states for each variable the CPT for any one of them has the number of cells equal to the product
