How do you calculate total number of combinations?
Combination Calculator. In finite mathematics a combination is most typically calculated using the formula C(n,r) = n!/r!(n-r)!. In this formula n represents the total number of items and r represents the number of items to choose. The formula is modified depending on the importance of item order and repeating items in the set of allowed results.
How to find the possible number of combinations?
Method 2 of 2: Calculating Combinations with Repetition Consider an example problem where order does not matter but repetition is allowed. In this kind of problem, you can use the same item more than once. Plug in your values for n {\\displaystyle n} and r {\\displaystyle r}. Solve the equation to find the number of combinations. You can do this either by hand or with a calculator.
What is the formula for the number of possible combinations?
The formula for combinations is generally n! / (r! (n — r)!), where n is the total number of possibilities to start and r is the number of selections made. In our example, we have 52 cards; therefore, n = 52.
