Let the sets `A={2, 4, 6, 8….} and B={3,6,9,12…}` such that `n(A)=200 and n(B)=250`. If `n(AuuB)=k,` then `(k)/(100)` is equal to

If A and B are two sets such that n(A)=70 ,\ n(B)=60 ,\ n(AuuB)=110 ,\ then\ n(AnnB) is equal to

Let A = {2, 4, 6, 8, 10, 12} and B = {3, 6, 9, 12, 15}. Find AuuB and AnnB .

Let n(U)=500. If A and B are such that n(A)=200, n(B)=300 and n(AcapB) =100 then n(A' cap B') is equal to:

Let U be the universal set for sets A and B such that n(A) =200 ,n(B) =300 and n(A cap B)=100. then n(A'cap B') is equal to 300, provided that n(U) is equal to

Let U be the universal set for sets A and B such that n(A) =200 ,n(B) =300 and n(A cap B)=100. then n(A'cap B') is equal to 300, provided that n(U) is equal to
