The students in Dr. Lee's math class are asked to vote on the starting time for their final exam. Their choices are M for 8:00AM, A for 10:00AM, T for 12NN, or H for 2:00PM. The results of the election are shown in the preference table below.

Using the plurality with elimination, was the majority criterion violated?
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.
