A straight flush is a poker hand that consist of 5 cards in a row of all the same suit (Diamonds, Hearts, Spades, or Clubs. Suppose you are playing video poker and are dealt 4 D,5 D, 6 D,7 D King C. The machine uses a normal 52 card deck (A, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen King). If I throw away the king and draw another card, what are your odds of making a straight flush? The King of Clubs you throw away cannot be selected again, but any other card other than the 4-7 of Diamonds can be selected.
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.

The fundamental counting principle is a rule that is used to count the total number of possible outcomes in a given situation.
