Many of the problems that engineers face involve randomly varying phenomena of one sort or another. But if characterized properly, even such randomness and the resulting uncertainty are subject to rigorous mathematical analysis. This book provides students with a fundamental understanding of random phenomena and a working knowledge of how to model and analyze such phenomena. It explains how to use probability and statistics appropriately to deal with uncertainty in engineering problems. Basing his approach on the principle of theoretical foundations before application, Dr. Ogunnaike presents a classroom-tested course of study for understanding, characterizing, modeling, and quantifying randomly varying phenomena.
