Ratio

A comparison of two quantities by division. It may be written using a colon or the word "to", but is more often written as a fraction.

Equivalent Ratio

Ratios that have the same value when simplified

Part-to-Whole

Percentages, fractions, and decimals are all different ways to represent a portion of a whole or a number.

Fair game

A game in which each player has an equally likely chance of winning.

Complement

The set of all outcomes in the sample space that are NOT included in the event.

Dependent

Where the outcome of one event affects the outcome of the other event.

For example, if you draw a playing card from a deck and do not replace it for the next draw, the next draw of a card would be affected because there would be one less card.

Independent

Where the outcome of one event does not affect the outcome of the other event.

For example, if you draw a card from a standard deck of playing cards but replace it before you draw again.

Probability Tree

A diagram that represents possible outcomes of probability experiments.

Mutually Exclusive

Two events that have no outcomes in common.

Systematic List

A list created by following an organized process. Helps to find all outcomes of a sample space or event when finding probabilities.

Probability Table

An area model that can organize probability outcomes if there are exactly two events. The possibilities for each event are listed on the sides and the combinations of outcomes are listed on the inside.

Scalene Triangle

A triangle with no congruent sides.

5-D Process

An organized method to solve problems, and include Describe/Draw, Define, Do, Decide, and Declare.

Consecutive Integers

Integers that are in order without skipping any integers. The numbers 8, 9, and 10 are an example of these.

Compound Events

An outcome that depends on two or more other events. An example is finding the probability that both a red ball AND also a blue block are drawn from a bag in two draws.
