Probability from Informal to Formal: Introduction to Probability.

Did you know that mathematics may help you to find a numeric value to the possibility that you win, or loose when playing with a deck of cards? Do you know how to determine the sample space, and/or the outcomes of an experiment? Do you understand what we referred as "experiment"?

Probability is a fascinating world, and for many persons full of fun when they play with spinners, dice, or a deck of cards. Solving probability problems sometimes requires that you draw diagrams or sketch the solution on a paper. At the top of the screen by the upper right hand you have the MARKER TOOLS menu to do preciscely that on the screen using the pen or your finger. As with any topic you have terms and definitions for those terms. You will find some of the associated to this lesson at the bottom of the screen. This lesson will guide you to the know-how's of finding probabilities when using combinations and permutations. Most will be able to determine your real chances in a chance game. So...go for the game!

Lesson's Glossary

Combination: Any arrangement in which order is not important.

Factorial! n! represents the product of all the whole numbers from n to 1. n! is the product of all the whole numbers from n down to 1 - used in probability.

Favorable outcome: The desired results of an experiment in probability.

Outcomes: The possible results of a probability experiment.

Permutation: Any arrangement in which order is important.

Probability: The possibility of an event to happen. The probability of getting an even number when rolling a 6 sided dice is 50%.

Sample Space: All possible ways an event may happen.

Theoretical Probability: The computation of the possibility that something will occur based on the number of possible outcomes.
