Key Concepts

• The probability of an event happening between [latex]a[/latex] and [latex]b[/latex] is written as [latex]P(a \leq x \leq b)[/latex].
• The total area under a continuous probability distribution function is [latex]1[/latex].

Glossary

continuous probability distribution: for a continuous probability distribution function, any value is possible within a given range of values. The probability is the same as the area under the continuous function.
