Define and calculate conditional probabilities

Conditional Probability Given two events \(A\) and \(B\), the conditional probability of event \(A\) occurring, given that event \(B\) has occurred, is the probability of event \(A\) and \(B\) occurring over the probability of event \(B\) occurring as shown by…

Define independence and calculate probability of independent events

Define independence and calculate probabilities of independent events 1.1 Defining Independence In probability and statistics, two events, \(A\) and \(B\), are said to be independent if the occurrence of event A does not affect the probability that the other event…

Calculate Probabilities Using Addition and Multiplication Rules

The Addition Rule The Addition Rule of Probability is a rule for determining is used to find the probability that event A or event B happens. It’s associated with the use of the conjunction “or.” For example, We may want…

Calculate probabilities of mutually exclusive events

Mutually Exclusive Events \(A\) and \(B\) are mutually exclusive events if \(A\) and \(B\) cannot both occur at the same time. For example, when a coin is flipped, it cannot land on both the head and tail simultaneously. Therefore, we…

Define set functions, Venn diagrams, sample space, and events & define probability as a set function on a collection of events and state the basic axioms of probability.

What Is Probability? In mathematics, probability is the branch that deals with numerical descriptions of the likelihood that events will occur or that propositions are true. Probability is a number between 0 and 1, with 0 representing impossibility and 1…
