Assume that you are given 4 number, display card ,means you have 5 cards and each card having some number written on it. Now assume that you can not have a look at more than 2 cards at a time to reveal the number written on the cards.How Many comparison you would require to have them arranged in ascending order according to the numbers written on the cards. Show working steps how?
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.
