A subset `P_1` is chosen and `A` is reconstructed by replacing the elements of `P_1`. The same process is repeated for subsets `P_1,P_2,....,P_m` with `m gt1`. The number of ways of choosing `P_1,P_2,....,P_m` so that `P_1 cup P_2 cup....cup P_m=A` is (a)`(2^m-1)^(mn)` (b)`(2^n-1)^m` (c)`(m+n)C_m` (d) none of these JEE Main 2018,JEE mains 2018 solutions,JEE mains cut off marks,JEE mains answer key,JEE mains Questions, JEE Mains previous year questions,Cheat code for JEE mains,JEE main crash course, Jee Mains preparation in last 48 hours, Instructions for JEE main exam, JEE mains online,How to score good marks in JEE, Chemistry question of JEE mains, Physics questions of JEE Mains, Last 10 year Jee mains questions,IIT JEE, JEE advanced
