Answer:
Step-by-step explanation
A=(1,2,5)
Hence, n(A) = 3, here n refers the number and n(A) means the numbers of set A. There is a formula of P(A) that is 2^n(A). P refers the power set. And the power set of any set A is the set of all subsets of A. P(A)= 2³ => 8 that means the total number of elements. So the total number of elements are
P(A)= {∅,(1),(2),(5),(1,2),(1,5)(2,5),(1,2,5)}
