Continuous Random Variables
In concept, the treatment of a continuous random variable does not differ from that of a discrete
random variable. However, we have to be extremely careful when dealing with the real numbers,
lest we run into problems

Introduction
So far, we have discussed probabilities from the angle of the mechanisms that generate them. In
some cases, we know these mechanisms very well for example, in dice throws or poker games
in which case, we can often cal

Preliminaries
Definition 1 A random variable is a function of an outcome, X = f (). In other words, it is
a quantity that depends on chance.
The domain of a random variable is the sample space . Its range can be the

Tutorial one: Simple probability rules.
In this tutorial, for calculating probability, you can only use + for mutually exclusive events (outcomes),
for independent events (outcomes), and Pcfw_A=1-Pcfw_ A , for any event A in a defined sample space.

Q1.
There is one error in one of five blocks of a program. To find the error, we test three randomly
selected blocks. Let X be the number of errors in these three blocks. Compute E(X) and Var(X).
