Probability
It is often necessary to “guess” about the outcome of an event in order to make a decision. Politicians study polls to guess their likelihood of winning an election. Teachers choose a particular course of study based on what they think students can comprehend. Doctors choose the treatments needed for various diseases based on their assessment of likely results. At a casino where people play games of chance, people select the games based on the belief that the likelihood of winning is good. Students may choose a course of study based on the probable availability of jobs.
Everyone has encountered or used probability at some point in their lives. In fact, most people have an intuitive sense of probability. Probability deals with the chance of an event occurring. In this chapter, we will learn how to solve probability problems using a systematic approach.
