Fair game
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.

Mutually Exclusive
Two events that have no outcomes in common.
Systematic List

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.
