There are three nursing positions that must be filled at Lilly Hospital. Position 1 is the day nursing supervisor; position 2 is the night nurse supervisor; and position 3 is the nursing coordinator position. There are 10 qualified candidates for all three positions. Determine the number of different ways these applicants can fill the positions.
Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
Counting Theory
The fundamental counting principle is a rule that is used to count the total number of possible outcomes in a given situation.
