Probability theory is based on the paradigm of a random experiment; that is, an experiment whose outcome cannot be predicted with certainty, before the experiment is run.In classical or frequency-based probability theory, we also assume that the experiment can be repeated indefinitely under essentially the same conditions. … Although most of the probability calculations we will conduct will be rather intuitive due to their simplicity, we start with two fun examples that will illustrate the interesting and sometimes complex nature of probability. Often, relying only on our intuition is not enough to determine probability, so we’ll need … See more Eventually we will need to develop a more formal approach to probability, but we will begin with an informal discussion of what probability is.
