# How to do probability

College algebra students learn How to do probability, and manipulate different types of functions.

## How To Calculate Probability (With Examples)

The formula to calculate the probability of an event is equivalent to the ratio of favorable outcomes to the total number of outcomes. Probabilities always range between 0 and 1. The general probability formula can be expressed as: Probability = Number of Favorable Outcomes / Total Number of Outcomes or P (A) See more
