Permutations and Combinations Basics

Before we discuss Permutations and Combinations formulas, we are going to have a look at what the words Combination and Permutation mean.

In simple terms, if the order doesn't matter, then we have a combination and if the order does matter then we have a permutation. A lot of times you might get confused between permutation and combination, so refer the differences Between Permutation and Combination discussed below.

One from lot 1 and two from lot 2 = 1 x 3C2 ways

All the balls from lot 2 = 3C3 ways

Add all the cases: 1 + 3 + 3 + 1 = 8 ways
