# MAT 221 - Probability Theory

## Course Objectives

1. . To provide the basic concepts of probability
2. To set up probability models for a range of random phenomena, both discrete and continuous
3. Developing critical thinking skills, and the abilities to apply techniques of calculus (i.e., derivatives, integration, infinite series) to assess the probability of an event.
