Answer 1

Answer:

16

Step-by-step explanation:

A = {a, b, c, d}

If ,the number of elements of a set is n, then the number of power set is 2ⁿ

Here, the no. of elements of set A is 4.

n(P(A)) = 2⁴ = 16

{{},{a},{b},{c},{d},{a,c},{a,b},{b,c},{a,d},{b,d},{c,d},{a,b,d},{a,b,c},{a,c,d},{b,c,d},{a,b,c,d} }
