Answer 2

By definition of power set: It is the set formed by all the subsets of a set.

By definition of cardinality of a set: It is the number of elements that a set has.

The formula to find the cardinality of the power set of any set is:

N (P) = 2 ^ N (S)

Where:

N (P) = cardinality of the power set of the set S

N (S) = cardinality of the set we want

So:

N (S) = 5

N (P) = 2 ^ N (S)

N (P) = 2 ^ 5

N (P) = 32

That is, from the set S of 5 elements, 32 subsets can be formed (including S and void Ф)
