Given the joint probability density function in tabular form, determine the joint cumulative distrubution function. In probability theory, a probability density function ( pdf ), or density of a continuous random variable, is a function whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the random variable would be.
