The number of unordered pair (A,B), of subsets of the set S = {1,2,3,4,5,6,7,8,9,10}. Such that `AnnB = O/` and `AuuB = S`, is

The number of ways of selecting 4 numbers from the set S={1,2,3,4,5,6,7,8,9} such that they are not consecutive,is

Let A={1,2,3,5,9,7} and B={1,2,3,4,5,6,7,8,9,10}, show that A subset B=B

If R = {2, 4, 6, 8} S = {3, 4, 6, 7} T = {1, 2, 3, 4} are three subsets of the Universal set U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} then prove (S nn T)' = S' uu T'

If A={1,2,3,4,5,6},B={0,2,4,6,8},then find AuuB,AnnB and A-B .

Let A={1,2,3,5,9,7} and B={1,2,3,4,5,6,7,8,9,10} , show that A subset B

If R = {2, 4, 6, 8} S = {3, 4, 6, 7} T = {1, 2, 3, 4} are three subsets of the Universal set U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} then prove R-S = R nn S'

If R = {2, 4, 6, 8} S = {3, 4, 6, 7} T = {1, 2, 3, 4} are three subsets of the Universal set U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} then find R-S'
