A Probability Mass Function is a function used to describe the liklihood of the outcome of a random event that has a finite number of possible outcomes. The domain is the range of possible outcomes of the ra...

The first step is to expand the expression. This can be done using the FOIL method. This means that we multiply the First, Outside, Inside and Last terms in the bracket.First: x . x = x 2 Outside: x . -6 = -...
