👉 In probability theory, a pair of events A and B is said to be co-exchangeable if they occur together with equal probabilities. This means that the occurrence of event A does not change the probability of event B occurring. In other words, if A occurs, so does B, and vice versa. For example, suppose we have two independent random variables X and Y, where P(X = 1) = p and P(Y = 1) = q. Then, X and Y
