# 8. CONTINUOUS RANDOM VARIABLES

### Course Information

You will learn how to:

• use a probability density function that may be defined as a piecewise function
• use the general result $E\left( g\left( x \right) \right) =\int { f\left( x \right) g\left( x \right) dx }$, where $f\left( x \right)$ is the probability density function of the continuous random variable $X$, and $g\left( x \right)$ is a function of $X$
• understand and use the relationship between the probability density function (PDF) and the cumulative distribution function (CDF), and use either to evaluate probabilities or percentiles
• use cumulative distribution functions of related variables in simple cases.
