Question

find the power set of A={a, {b,c}, d}

Answer 1

Power set of a set A is a set of all subsets of A

So,

A = {a, {b, c}, d}

p(A) = { {a} , {{b,c}} , {d} , {a, {b,c}} , {a,d} , {{b,c},d} , {ɸ}, ɸ }

Answer 2

Answer:

Power set of A ={a, b, c, d}

Step-by-step explanation:

P(A) = { { },{a},{b},{c},{d},{a, b},{a, c},{a, d},{b, c},{b, d},{c, d},{a, b, c}{a, b, d},{b, c, d},{d, b, a}{a, b, c, d} }

n[P(A)] = 16
