Let X, Y be two RV's and we do not assume that they are independent. Now we are asking questions about the distribution of X given Y. As you stated, the conditional PDF of X given Y is. f ( X = x Y = y) = f ( X = x, Y = y) f ( Y = y) For the ease of understanding, we can define a new continuous variable Z y that is equal in … stratmann essen theater programm
