Please explain Suppose that A and B are conditionally independent given C. Suppose that P(C) > 0 and P(C^c) > 0. (a) Are A and B^c guaranteed to be conditionally independent given C? (b) Are A and B guaranteed to be conditionally independent given C^c?

00:01 Hello students, so here we are given suppose events a and b are conditionally independent are conditionally independent given c given c suppose p of c greater than 0 and p of c complement greater than 0 first question is asked are a and b guaranteed to be conditionally independent given c so the answer is yes a and b are a and b are guaranteed to be conditionally independent given c the fact that events a and b are conditionally independent given c implies that conditional probability of a given c is equal to unconditionally probability of a and unconditional probability of b given that c is equal to…
