Random Variables: Say you were to take a coin from your pocket and toss it into the air. Discrete Random Variables: Consider our coin toss again. Continuous Random Variables: Mixed Random Variables: Cumulative Distribution Functions (CDF): Probability Density Functions (PDF): Interactive CDF/PDF Example:
5.2.2 Joint Cumulative Distribution Function (CDF). We have already seen the joint CDF for discrete random variables. The joint CDF has the same definition for continuous random variables. It also satisfies the same properties. The joint cumulative function of two random variables X and Y is defined as. F X Y ( x , y ) = P ( X
Assuming that you would like to know the basics of PDF, CDF and their differences, let me explain these terms with the help of simple examples of probability. As an introductory concept, it is easy to understand probability in discrete systems. Discrete System As we know, tossing a coin gives 0.5 times head and 0.5 times tail

Example. Suppose the p.d.f. of a continuous random variable X is defined as: f(x) = x + 1. for ?1 < x < 0, and. f(x) = 1 ? x. for 0 ? x < 1. Find and graph the c.d.f. F(x). Solution. If we look at a graph of the p.d.f. f(x):. Picture of p.d.f. f(x). we see that the cumulative distribution function F(x) must be defined over four intervals — for x
If p(x) is a probability density function (pdf), then Example. Someone claims this is the. CDF for grades on the 2015 final exam. Probability a random student scored. • 25 or lower? 1, or 100%. • 50 or lower? Example. Sketch the density function for the cdf shown. Slope? 0. Slope 1/2. Slope 0. Slope 1/2. Slope 0
Cumulative Distribution Function (c.d.f.). • The c.d.f. of a continuous RV is defined exactly the same as for discrete RVs: F(x) = P(X ? x) = P(X ? (??,x]). • Hence F(x) = ? x. ?? f(x)dx, and differentiating both sides we get. dF dx. = f(x). Example. Suppose the lifetime, X, of a car battery has P(X>x)=2?x. Find the p.d.f. of. X. 5
