What is the number of combinations of 5 objects taken all at once?
120 arrangements
Thus, for 5 objects there are 5! = 120 arrangements.) For combinations, k objects are selected from a set of n objects to produce subsets without ordering.
How do you find the number of combinations?
To calculate combinations, we will use the formula nCr = n! / r! * (n – r)!, where n represents the total number of items, and r represents the number of items being chosen at a time. To calculate a combination, you will need to calculate a factorial.
How many combinations are there of 5 numbers without repeating?

How many combinations of 5 items are there?
Note that your choice of 5 objects can take any order whatsoever, because your choice each time can be any of the remaining objects. So we say that there are 5 factorial = 5! = 5x4x3x2x1 = 120 ways to arrange five objects. In general we say that there are n!

How many combinations of 6 items are there?
It’s the same as possibilities to a 6 digit code with known numbers and no repeats. With 1 item there are 6 possibilities with 2 you only have 5 choices after the first if you don’t repeat the same item. So for 6 items the equation is as follows 6*5*4*3*2= 720 possible combinations of 6 items.
