Have you ever wondered what your chances are of winning the main prize in a lottery? How probable is winning the second prize? To answer both and similar questions, you need to use combinations. We've got a special tool dedicated to that kind of problem. Our lottery calculator doesn't only estimate combination probability of winning any lottery game, but also provides a lottery formula. Try it! You'll find out how big (or small) those numbers are, in fact. You might also be interested in a convenient way for writing down very long numbers called scientific notation.

The Permutation (nPr) and Combination (nCr) work with steps shows the complete step-by-step calculation for finding the the number of ways in which we can choose \$8\$ different objects out of a set containing \$10\$ different objects, where the order of the elements is important. For any other values of the total number of objects and sample size, just supply two positive integers and click on the GENERATE WORK button. The grade school students may use this permutation and combination calculator to generate the work, verify the results of the combinatorics, probability and statistical problems or do their homework problems efficiently.
