The probability of an event represents the likelihood it will occur.

Probability compares the favorable number of outcomes to the total number of outcomes. \[P(E) = \frac{{{\rm{favorable\: number\: of\: outcomes}}}}{{{\rm{total\: number\: of \:outcomes}}}}\]

The favorable number of outcomes is called the event.

The total number of outcomes is called the sample space.

Probability can be expressed as a fraction, decimal, or percentage.

There are two types of probability:

1. Theoretical probability is found using mathematics.

2. Experimental probability is found by conducting an experiment.

Introduction to Probability

In statistics, a fundamental concept found in the introduction to probability. When dealing with the introduction to probability, students first encounter basic problems that calculate the likelihood of an event occurring, an event such as drawing a specific card from a deck. Terms from an introduction to probability include an event, its complement and the sample space.

This video introduces probability and determine the probability of basic events.

We give you an introduction to probability through the example of flipping a quarter and rolling a die.

This video shows the basic idea and a few simple examples of calculating the probability of simple events.
