यदि (n(U)=75), (n\(A\cap B\)=18) है, तो (n(\(A\cap B\)^c)) कितना होगा?

If (n(U)=75) and (n\(A\cap B\)=18), what is (n(\(A\cap B\)^c))?

Explanation opens after your attempt
Correct Answer

A. (57)

Step 1

Concept

The complement is found by subtracting from (U), so (75-18=57). Here the complement of only the common part is asked.

Step 2

Why this answer is correct

The correct answer is A. (57). The complement is found by subtracting from (U), so (75-18=57). Here the complement of only the common part is asked.

Step 3

Exam Tip

पूरक (U) से घटाकर मिलता है, इसलिए (75-18=57)। यहां केवल साझा भाग का पूरक पूछा गया है।
