<p>Conditional Probability: The probability of an event occurring given that another event has already occurred. Independent Events: Two events that do not affect each other's occurrence. Dependent Events: Two events where the occurrence of one affects the probability of the other. Probability: A measure of the likelihood that an event will occur, expressed as a<a>number</a>between 0 and 1. Event: An outcome or a specific<a>set</a>of outcomes of a<a>random experiment</a>.</p>
