Permutation -- From MathWorld A permutation, also called an "arrangement number" or "order," is a rearrangement of the elements of an ordered list S into a one-to-one correspondence with S itself. The number of permutations on a set of n elements is given by n! (n factorial; Uspensky 1937, p. 18). For example, there are 2!==2.1==2 pe Searched for "combination". Results 1 - 10 of about 105. Combination -- From MathWorld The number of ways of picking k unordered outcomes from n possibilities. Also known as the binomial coefficient or choice number and read "n choose k," _nC_k=(n; k)=(n!)/(k!(n-k)!), where n! is a factorial (Uspensky 1937, p. 18).

The function name is COMBIN.

Excel's PERMUT function for =Permut(45.6) returns odds of 5,864,443,200 This seems too excessive, it's more like the odds of picking the 6 numbers in numerical order. |
