Say for question 11, to find the marginal distribution of X, you just add the columns in the table and that gives you the marginal distribution of X. The same thing goes for conditional distribution.yvonne_710 said:can i ask, how to calculate marginal distribution and coniditional distribution?thanks~!!!!!!!!
