Introduction to Probability & Reliability Statistics Module

In preparation for the reliability methods and tools to follow, this module covers many of the fundamental building blocks.  Since Reliability is a probability, we review some essential probability ideas and rules.  We introduce the concept of conditional probability since it plays a role in various methods such as warranty forecasting and burn-in.  We discuss probability models that may be considered in describing time-to-failure data with some emphasis on the Weibull distribution.  The Weibull distribution is very popular due to its flexibility and meaningful parameters although we should not limit ourselves solely to this model.  Finally, we discuss some useful discrete distribution models and their applications to reliability.
