1. Random Variables and Probability Distributions illustrates a random variable. distinguishes between a discrete and a continuous random variable. finds the possible values of a random variable.

2. PROBABILITY Probability is a field of mathematics that deals with CHANCE. An Experiment is an activity in which the result cannot be predicted with certainty. Each repetition of an experiment is called a trial. An outcome is a result of an experiment. An event is any collection of outcomes, and a simple event is an event with only one possible outcome. The sample space for a given experiment is a set S that contains all possible outcomes of the experiment. In an experiment for which the sample space is S, the probability of an event occurring is given by the formula.
