== Introductory topics in combinatorics ==
+
An introduction to [[combinatorics]] concerns mostly [[counting]] and [[probability]]. As problem-solving ability becomes more advanced, the scope of combinatorics grows, leading students to the [[Combinatorics/Intermediate | intermediate]] level.
The following topics provide a good study in introductory combinatorics.
