A person owns three suits, three ties and ten shirts. How many ways can They select a traveling wardrobe of two suits four ties and six shirts?
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.
A person owns three suits, three ties and ten shirts.
To find the number is ways of selection of two suits, four ties and six shirts.
Here, 4 ties cannot be selected from 3 ties available.
So, number of ways of selection of tie = 0
