120
There are 120 permutations and 5 combinations.
120 ABCDE , there are 120 ways these five letters can be rearranged.
5 factorial is just a number .... namely, 120 . If you want to see all of the 120 'permutations' of five objects, simply do this: -- List all of the 5-digit numbers from 01,234 to 43,210. -- Cross off every number on the list that has any digit greater than 4 in it. -- Cross off every number on the list that has any repeated digit in it. You'll have all of the 120 permutations of the objects 0, 1, 2, 3, and 4, without repetition.
120 WRONG! That is the number of PERMUTATIONS. In the case of combinations, the order of the numbers does not matter, so there is only 1 5-number combination from 5 numbers.
120 5x4x3x2x1=120

5! = 5x4x3x2x1 = 120

There are 120 combinations of 5 items, which can be calculated using the formula nCr = n! / r!(n - r)!.
120 5 x 4 x 3 x 2 x1 = Toppings 20 x 6 x 1 = Toppings 120 x 1 = Toppings 120 = Topping Combinations
It can have 120 combinations . . .
Possible 5 digit combinations using 5 digits only 1 time is 5! or 5*4*3*2*1 or 120. Using 5 digits where numbers can be used 5 times is 55 or 3125.
3*5*8 = 120
