Permutations and combinations: Learn the basics of

Learn the basics of Permutation and Combination, important formulas, and solved examples to easily understand how to arrange and select objects in different ways. Permutation and combination are the methods employed in counting how many outcomes are possible in various situations. Permutations are understood as arrangements and combinations are understood as selections. Permutation is the arrangement of items in which the order of selection matters. Combination is selecting items without considering order. For example, in the below diagram, PQ and QP are different in permutation but same in combination. Therefore we have more permutations than combinations. Learn the basic counting techniques of permutations and combinations with examples and exercises. Find out how to apply the fundamental principle of counting, the multiplication principle and the addition principle to solve problems involving arrangements and selections of objects.
