This table tells us that the probability that X takes the value of -2 while Y simultaneously takes the value of 3 is 0.27 and that the probability that X takes the value of 3 while Y takes the value of 6 is 0.35, and so on.
In relation to f (x, y), f (x) and f (y) are called individual, or marginal, probability density functions. These marginal PDFs are derived as follows:
marginal PDF of X marginal PDF of Y
where, for example, y means the sum over all values of Y and x means the sum over all values of X.
