If \(A={\varnothing,{1}}\), then what is (n(P(A)))?
Explanation opens after your attempt
C. (4)
Concept
(A) has two elements, \(\varnothing\) and ({1}), so (n(P(A))=22=4). The empty set can also be an element.
Why this answer is correct
The correct answer is C. (4). (A) has two elements, \(\varnothing\) and ({1}), so (n(P(A))=22=4). The empty set can also be an element.
Exam Tip
(A) में दो अवयव \(\varnothing\) और ({1}) हैं, इसलिए (n(P(A))=22=4)। खाली समुच्चय भी अवयव हो सकता है।
