con·di·tion·al prob·a·bil·i·ty

a probability quoted when the range of choices admitted is restricted, that is, conditional; thus, the probability of the child of a color-blind man inheriting the gene is 1/2 if the child is female and almost 0 if the child is male.

The network has two components: (1) a DAG G = ([R.sub.n], [M.sub.r]) that represents the structural arrangement of a set of variables (nodes) [R.sub.n] = ([x.sub.1], ..., [x.sub.n]} and a corresponding set of dependence and independence assertions (arcs) [M.sub.r] between the variables; (2) a set of conditional probability distributions P = {[p.sub.i], ..., [p.sub.n]} between the parent and the child nodes in the graph.
