1. How would yiu determine if the situation involves combination? 2. How do you illustrate the combination of objects? 3. For you, what is the most convenient method to use?
1. In a combination problem, the important thing is whether something is picked or not (vs. the order). If the order at which something is picked is important, the problem deals with permutation. Usually, if there are specific things associated with the order of picking, those are permutations and not combination.
2. These combinations (subsets) are enumerated by the 1 digits of the set of base 2 numbers counting from 0 to 2n − 1, where each digit position is an item from the set of n. Representing these subsets (in the same order) as base 2 numerals: 0 – 000. 1 – 001.
