\(यदि (A={x:x\in\mathbb{N},x\le 12}), (B={x:x\in\mathbb{N},x\) अभाज्य है\(}) और (B) को (A) तक सीमित माना गया है, तो (A\setminus B) क्या है\)?

\(If (A={x:x\in\mathbb{N},x\le 12}), (B={x:x\in\mathbb{N},x\) is prime\(}), and (B) is restricted to (A), then what is (A\setminus B)\)?

Correct Answer

A. ({1,4,6,8,9,10,12})

Step 1

Concept

The prime elements in (A) are ({2,3,5,7,11}). Removing them gives ({1,4,6,8,9,10,12}).

Step 2

Why this answer is correct

The correct answer is A. ({1,4,6,8,9,10,12}). The prime elements in (A) are ({2,3,5,7,11}). Removing them gives ({1,4,6,8,9,10,12}).

Step 3

Exam Tip

(A) में अभाज्य तत्व ({2,3,5,7,11}) हैं। उन्हें हटाने पर ({1,4,6,8,9,10,12}) मिलता है।
