A deck consists of 110 cards with 11 suits labelled A to K and numbered ranks from 1 to 10. That is, there are 10 cards of each suit and 11 cards of each rank. Suits A to E are red. Suits F to K are blue. A card is drawn at random from this deck. What is the probability of it being suit C and having rank 7?
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 deck consists of 110 cards with 11 suits labelled A to K and numbered ranks from 1 to 10. That is, there are 10 cards of each suit and 11 cards of each rank.
Suits A to E are red.
Suits F to K are blue.
A card is drawn at random from this deck.
