nCr:nCris known as a combination, which is the method of selection of 'r' objects from a set of 'n' objects where the order of selection does not matter. To find the value of nCr, we use the formula: nCr = n!/[r

Combination is the selection of data from the given in a without the concern of arrangement. Permutation and combination differs in the sense that permutation is the process of arranging whereas combination is the process of selection of elements from the given set. Formula for permutation is -:...
