In a standard deck of 52 playing cards, the cards are broken down into 4 suits of 13 cards each. The 13 hearts and 13 diamonds are all red cards, while the 13 clubs and 13 spades are all black cards. If you shuffle the deck thoroughly and select one card at random, then what is P("your card is a red card" | "your card is a heart")?
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.
