Statistics math problems

Probability is simply how likely something is to happen. Whenever we’re unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics. View all of Khan Academy’s lessons and practice exercises on probability and statistics.
