Maximum : The maximum of a set of numbers is the highest of the numbers in the set. A function has a maximum at $x_0$ if $f(x_0)\geq f(x)$ for all $x.$

Minimum : The minimum of a set of numbers is the lowest of the numbers in the set. A function has a minimum at $x_0$ if $f(x_0)\leq f(x)$ for all $x.$

Minus : Minus is either a symbol or another word for subtraction.

Number : A number $x$ is a mathematical symbol representing a quantity.

Range : The range of n numbers is the difference between the largest and the smallest number. The range of a function $f$ is the set of all possible values $f(x).$ For example the range of the function $f(x)=x^2$ is the interval $[0,\infty).$

Maximum : The maximum of a set of numbers is the highest of the numbers in the set. A function has a maximum at $x_0$ if $f(x_0)\geq f(x)$ for all $x.$

Number : A number $x$ is a mathematical symbol representing a quantity.

Impossible : An event is impossible if it has a probability of 0.

Outcome : A result of a random experiment.

Probability : A probability is a number between 0 and 1 that describes how likely an outcome is. For discrete events that are equally likely the probability can be calculated by dividing the number of favorable outcomes by the number of possible outcomes.

Ten thousandth : Ten thousandth refers to the number $\frac{1}{10,000}=0.0001=10^{-4}.$

Unlikely : An event in a probability experiment in unlikely if the probability of it happening is low.
