Lecture 9: Expectation, Indicator Random Variables, Linearity (STAT 110)

Professor

50:23·2013·undergraduate level

This lecture introduces expected values, exploring indicator random variables and the principle of linearity to calculate means. It also establishes the fundamental bridge between probability and expectation and presents the Geometric distribution.

We discuss expected values and the meaning of means, and introduce some very useful tools for finding expected values: indicator r.v.s, linearity, and symmetry. The fundamental bridge connects probability and expectation. We also introduce the Geometric distribution.
