\(यदि (U={x:x\) एक अंक है\(}) और (A={x:x\) अभाज्य अंक है\(}), तो (n(A^c)) कितना होगा\)?
\(If (U={x:x\) is a digit\(}) and (A={x:x\) is a prime digit\(}), what is (n(A^c))\)?
Explanation opens after your attempt
A. (6)
Concept
The prime digits are (2,3,5,7). There are (10) digits in all, so the complement has (10-4=6) digits.
Why this answer is correct
The correct answer is A. (6). The prime digits are (2,3,5,7). There are (10) digits in all, so the complement has (10-4=6) digits.
Exam Tip
अंकों में अभाज्य अंक (2,3,5,7) हैं। कुल (10) अंक हैं, इसलिए पूरक में (10-4=6) अंक होंगे।
