Text : Quantifying Uncertainty
Epigraph :
"The most important questions of life are, for the most part, really only problems of probability."
Marquis de Laplace
Probability plays a special role in our lives, because we use it to measure uncertainty. We are continually faced with decisions that lead to uncertain outcomes, and we rely on probability to help us choose our course of action. In business, probability is a pivotal factor in most significant decisions. A department store buyer will order large quantities of a new style that is predicted to sell well. A company will introduce a new product when the chance of its success seems high enough to outweigh the possibility of losses due to its failure. A new college graduate is hired when the probability for satisfactory performance is judged to be sufficiently high $\ldots$
A probability is numerical value that measures the uncertainty that a particular event will occur. The probability for an event ordinarily represents the proportion of times under identical circumstances that the event can be expected to occur. Probability theory treats a probability as a number. Such numbers, too, are common. We are all familiar with the weather forecaster's announcement that "there is a $50\%$ chance of rain tomorrow". We may extend our understanding of probability to a family of experiments. The simplest of which is the coin toss, for which there is a $50\%$ chance of obtaining either outcome : head or tail.
