Basic Probability

Abstract

We now begin the formal st udy of probability. We do so by utilizing t he properties of sets in conjunction with the axiomatic approach to probability.In particular,we will see how to solve a class of probability pr oblems via counting methods. These are problems such as determining the probability of obtaining a royal flush in poker or of obtaining a defective item from a batch of mostly good items,as examples. Furthermo re, the axiomatic approach will provide t he basis for all our further studies of probability.Only t he methods of determining the probabilities will have to be mod ified in accordance wit h t he problem at hand.
