Answer 2

Step-by-step explanation:

If A={a, b, c, d}, then how many subsets does the set A have?

A set having n members has 2n subsets. This number includes the empty set and the given set.

The set A has 4 members, so it has 24=16 subsets.

They are: ∅ ( = { }), {a}, {b}, {c}, {d}, {a, b}, {a, c}, {a, d}, {b, c}, {b, d}, {c, d}, {a, b, c}, {a, b, d}, {a, c, d}, {b, c, d}, {a, b, c, d}.
