Key Concepts

Law of Total Probability

The Law of Total Probability is a rule that provides a way to compute the probability of an event by considering all possible mutually exclusive scenarios leading to that event. It breaks down a complex probability problem into simpler parts, each corresponding to different conditions or cases, and then sums the probabilities over these cases.

Probability

Probability is a measure of how likely an event is to occur, expressed as a number between 0 and 1. In problems involving chance, such as drawing balls from boxes, probability quantifies the likelihood of outcomes, enabling us to predict the frequency of an event in the long run.

Conditional Probability

Conditional probability refers to the probability of an event occurring given that another event has already occurred. This concept is crucial when the outcome of one event influences the probabilities of subsequent events, as in multi-step experiments where the result of the first selection affects the conditions for the next selection.
