यदि (n(U)=105) और (n\(A\cap B\)=37) है, तो (n(\(A\cap B\)^c)) कितना होगा?
If (n(U)=105) and (n\(A\cap B\)=37), what is (n(\(A\cap B\)^c))?
Explanation opens after your attempt
A. (68)
Concept
The complement is found by subtracting from (U), so (105-37=68). Here the complement of only the common part is asked.
Why this answer is correct
The correct answer is A. (68). The complement is found by subtracting from (U), so (105-37=68). Here the complement of only the common part is asked.
Exam Tip
पूरक (U) से घटाकर मिलता है, इसलिए (105-37=68)। यहां केवल साझा भाग का पूरक पूछा गया है।
