Currently studying for a test and noticed this problem
2.1.23. How many elements does each of these sets have where a and b are distinct elements?
A. P({a, b, {a, b}})
B. P({∅, a, {a}, {{a}}})
C. P(P(∅))
For whatever reason this was not covered in class (It's not in my notes and i take notes in that class religiously) Was wondering if anyone knew how the hell do this, the book we were assigned does a poor job of explaining it, or anything for that matter.
