Question

If A = {x : x ε [p , q]where p , q, x ε N} ,then what is the value of
n [ P( A)], where P(A) denotes the power set of A.

Answer 1

Step-by-step explanation:

we know that,

$P(A) = {2}^{m} \: where \: m \: is \: number \: of \: elements \: in \: the \: set$

A={p,q}

$P(A) = {2}^{2}$

$\boxed{P(A) = 4}$

Hence it will contains four elements
