K problems with solutions N choose K table Combinations vs permutations. To determine the number of combinations the following formula is used: Free online combination calculator, supports repeating and non-repeating. Press MATH and use the right arrow key to scroll over to the PRB. The calculator interface consists of one drop-down menu labeled Type with two options. The combinations are defined as the number of ways in which a sample of r elements can be selected from n distinct objects that's why it is also referred as 'n choose r'. To Calculate the number of Permutations or Combinations Input the total number of objects, n. The Combination and Permutation Calculator is an online tool that calculates the number of possible permutations n P k or combinations n C k for n items taken k at a time and also displays each combination and permutation as elements in a set. Permutations Calculator Use this calculator to easily calculate the number of permutations given a set of objects (types) and the number you need to draw from the set. It is read as the number of possible Permutation of selecting a subset 'r' from 'n' distinct objects. To determine the number of Permutation the following formula is used: The permutations are defined as the number of possible ways to select a subset (r) from a larger set of objects (n), however the order of subset matters here.
