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.
Ratios that have the same value when simplified
Percentages, fractions, and decimals are all different ways to represent a portion of a whole or a number.
A game in which each player has an equally likely chance of winning.
The set of all outcomes in the sample space that are NOT included in the event.
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.
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.
A diagram that represents possible outcomes of probability experiments.
Two events that have no outcomes in common.
A list created by following an organized process. Helps to find all outcomes of a sample space or event when finding probabilities.
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.
A triangle with no congruent sides.
An organized method to solve problems, and include Describe/Draw, Define, Do, Decide, and Declare.
Integers that are in order without skipping any integers. The numbers 8, 9, and 10 are an example of these.
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.
