Hopefully you are convinced that uncertainty is all around us, in our daily lives and in many
professions. How can probability theory help us survive, and even thrive, in the face of such
uncertainty? Probability theory:
• provides a language for people to discuss/communicate/aggregate knowledge
about uncertainty. Use of standard deviation is widely used when results of opinion polls
are described. The language of probability theory lets people break down complex problems,
and to argue about pieces of them with each other, and then aggregate information about
subsystems to analyze a whole system.
• provides guidance for statistical decision making and estimation or inference.
The theory provides concrete recommendations about what rules to use in making decisions
of inferences, when uncertainty is involved.
• provides modeling tools and ways to deal with complexity. For complex situations,
the theory provides approximations and bounds u...
