In the module Relationships in Categorical Data with Intro to Probability, we used the word probability to mean “likelihood” or “chance.” We represent a probability with this notation: P(A) where A is the description of the outcome. For example, suppose we randomly select a student from your college and we want to know the probability that we select a female student. The outcome A represents a female student. P(A) represents the probability (or likelihood) that the randomly selected student is a female.

The probability is a number between 0 and 1. What does this number tell us about the likelihood of an event occurring? Watch this short video to answer that question.
