Question

if set A={1} how many elements of P[P {P (A)}] contains

Answer 1

Answer:

16

Step-by-step explanation:

Number of elements in P(A) = 2^1 = 2 (number of elements in a power set = 2^n, where n is the number of elements of the set)

Number of elements in P{P(A)} = 2^2 = 4 (as P(A) has 2 elements)

Number of elements in P[P{P(A)}] = 2^4 = 16 (as P{P(A)} has 4 elements)
