Find the value of each of the following using the appropriate formula. 6!= Enter you answer; 6! 10!= Enter you answer; 10! (7-1) != Enter you answer; (7-1)! (17-9) != Enter you answer; (17-9)! C92= Enter you answer; 9C2 C50= Enter you answer; 5C0 C55= Enter you answer; 5C5 C75= Enter you answer; 7C5 C127= Enter you answer; 12C7 P74= Enter you answer; 7P4 P95= Enter you answer; 9P5
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.
Find the value of each of the following using the appropriate formula.
6!= Enter you answer; 6!
10!= Enter you answer; 10!
(7-1) != Enter you answer; (7-1)!
(17-9) != Enter you answer; (17-9)!
