Detailed Solution
Download Solution PDFধারণা:
- দুটি সেটের পার্থক্য: A এবং B দুটি সেট হলে, A - B = {x : x ∈ A এবং x∉ B}
গণনা:
প্রদত্ত: A - B = ϕ
আমরা জানি যে, A এবং B দুটি সেট হলে, A - B = {x : x ∈ A এবং x∉ B}
সুতরাং, যদি A - B = ϕ হয়, তাহলে A এর সমস্ত উপাদান B-তেও রয়েছে।
আমরা জানি যে, যদি A এর সমস্ত উপাদান B তে থাকে তবে, A ⊂ B
অতএব, বিকল্প 2 সঠিক।
