What are Permutation and Combination?
The Fundamental Principle of Counting is a unique way to find out the total number of ways events can occur
throughout the process. The process involves the occurrence of more than one event or activity.
It can be explained as: If there are m ways for one event to occur and n ways for the second activity to occur then
there will be m•n ways for both the events to occur.
Permutations are the set of objects or events where order or position is important. In other words,
Permutation is the act of arranging all the objects or members of the event in some sequence. The permutation is
denoted as: n_(P_r )
Combinations are the set of objects or events where the order or position is not important. Combination
is basically defined as the way of selecting the objects or members of the events.
The Combinations are denoted as: n_(C_r )
