MATH 108: Quantitative Literacy

Credit Hours

3

Prerequisites

None. Fulfills CORE Quantitative Analysis requirement.

Description

An introduction to mathematical modeling. Topics chosen from linear programming, probability theory, Markov chains, scheduling problems, coding theory, social choice, voting theory, geometric concepts, game theory, graph theory, combinatorics, networks. Emphasis placed upon demonstrating the usefulness of mathematical models in other disciplines, especially the social sciences and business.
