Imagine you’re running a basketball camp. You have all 20 athletes put their name in the cap, and you pull out 5 at random to create a team. a. How many different combinations of teams could you pull? b. How many time more permutations are there than combinations
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.
Imagine you’re running a basketball camp. You have all 20 athletes put their name in the cap, and you pull out 5 at random to create a team.
a. How many different combinations of teams could you pull?
