Combinations and Permutations Calculator Find out how many different ways to choose items. For an in-depth explanation of the formulas please visit Combinations and Permutations .


Calculator Use The Combinations Calculator will find the number of possible combinations that can be obtained by taking a sample of items from a larger set. Basically, it shows how many different possible subsets can be made from the larger set. For this calculator, the order of the items chosen in the subset does not matter.


Combinations and Permutations Calculator Find the number of combinations and/or permutations that result when you choose r elements from a set of n elements. For help in using the calculator, read the Frequently-Asked Questions or review the Sample Problems. Choose the goal of your analysis (i.e., to compute combinations or permutations).


Possible Outcomes Calculator The chances of an event to occur is called as the possible outcome. Consider, you toss a coin once, the chance of occurring a head is 1 and chance of occurring a tail is 1. Hence, the number of possible outcomes is 2.


This combination calculator (n choose k calculator) is a tool that helps you not only determine the number of combinations in a set (often denoted as nCr), but it also shows you every single possible combination (permutation) of your set, up to the length of 20 elements.


Probability Calculator You can use this Probability Calculator to determine the probability of single and multiple events. Enter your values in the form and click the "Calculate" button to see the results. Single Event Probability Calculator


Combination Calculator to Find All Possible Combinations of Numbers or Letters This combination generator will quickly find and list all possible combinations of up to 7 letters or numbers, or a combination of letters and numbers. Plus, you can even choose to have the result set sorted in ascending or descending order.


Another possible scenario that the calculator above computes is P (A XOR B), shown in the Venn diagram below. The "Exclusive OR" operation is defined as the event that A or B occurs, but not simultaneously. The equation is as follows:
