Binomial coefficient latex

So we need to decide "yes" or "no" for the element 1. And for each choice we make, we need to decide "yes" or "no" for the element 2. And so on. For each of the 5 elements, we have 2 choices. Therefore the number of subsets is simply 2 ⋅ 2 ⋅ 2 ⋅ 2 ⋅ 2 = 25 (by the multiplicative principle).
