Boolean Algebra --এর নিচের কোনটি সঠিক? Correct Answer A + A' = 1

১৮৪৭ সালে ইংরেজ গণিতজ্ঞ জর্জ বুল (George Boole ) সর্বপ্রথম বুলিয়ান অ্যালজেবরা মূলত লজিকের সত্য এবং মিথ্যা এই দুইস্তরের উপর ভিত্তি করে তৈরি হয়েছে। এ পদ্ধতিতে শুধুমাত্র বুলিয়ান গুণ ও যোগের সাহায্যে সমস্ত সমাধান করা হয়। এক্ষেত্রে ব্যবহৃত উপপাদ্য ১০ টি । এদের মধ্যে মৌলিক কয়েকটি হলো - (i) A + 0 = A, (ii) A.1 = A; (iii) A + A = 1 , iv. A.A = 0; v. A + A = A. vi. A.A = A; Vii. A + 1 = 1 ; viii = A.0 = 0   উত্তর ভুল আছে।    A + A = 1 তঠিক আছে তো

The Coordinator of an International Virtual Conference has planned six guest lectures on different areas-Cryptography, Fluid Dynamics, Big Data Analysis, Wavelet Theory, Differential Equations and Linear Algebra-to be organised only one on each day from Monday to Sunday.  Wavelet Theory should be organised immediately after Differential Equations.  Big Data Analysis should be organised on Wednesday and should not be followed by Linear Algebra.  Fluid Dynamics should be organised on Friday and there should be a gap of two days between Cryptography and Linear Algebra.  One day there will be no lecture (Saturday is not that day), and just before that day Linear Algebra will be organised. How many lectures are organised between Big Data Analysis and Wavelet Theory?
