Find the number of ways of choosing r unordered outcomes from n possibilities as nCr (or nCk). Combinations calculator or binomial coefficient calcator and combinations formula. Free online combinations calculator.
The "has" rule which says that certain items must be included (for the entry to be included). Example: has 2,a,b,c means that an entry must have at least two of the letters a, b and c. The "no" rule which means that some items from the list must not occur together. Example: no 2,a,b,c means that an ...
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. Selecting items from a set without considering the order is called as combination.
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.
This free calculator can compute the number of possible permutations and combinations when selecting r elements from a set of n elements.

This free probability calculator can calculate the probability of two events, as well as that of a normal distribution. Learn more about different types of probabilities, or explore hundreds of other calculators covering the topics of math, finance, fitness, and health, among others.
This calculator which generates possible combinations of m elements from the set of element with size n. Number of possible combinations, as shown in Combinatorics.Combinations, arrangements and permutations is. The description of generator algorithm is below the calculator
Review the formula for 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. We want to select 13 cards, so r = 13.
How calculate the number of possible different variations? Ask Question 3. 2 $\begingroup$ I feel stupid, but I don't know how to calculate how many possible variations I can get from for example three spaces (1|2|3) Normally I'd say: "well that is easy, just take the number of spaces (=3) and 3^3"
Combinations and Permutations What's the Difference? In English we use the word "combination" loosely, without thinking if the order of things is important. In other words: "My fruit salad is a combination of apples, grapes and bananas" We don't care what order the fruits are in, they could also be "bananas, grapes and apples" or "grapes, apples and banan...
