Prove that , U = `(U -A) + A, `Where U is the universal set .

Given n(U) = 20, n(A) = 12, n(B) = 9, n(AnnB) = 4, where U is the universal set, A and B are subsets of U, then n((AuuB)') equals

If n(U)=50, n(A)=24, and n(B)= 30 where U is the universal set, then find (i) The greatest value of n(A cup B) (ii) The least value of n(A cap B)

If n(U)=60, n(A)=26 and n(B)=36 where U is the universal set then find: (i) The greatest Value of n(A cup B) (ii) The least value of n(A cap B) .

If n(U)=1200, n(A)=900 and n(B)=700 where U is the universal set then find: (i) The greatest value of n(A cup B) (ii) The least value of n(A cap B) .

Choose the correct answer: 1. If A, B and C are three sets and U is the universal 6 set such that n(U) = 700, n(A) = 200, n(B) = 300 and n(A n B) = 100. Find n(A' n B')

|X| represent number of elements in region X. Now the following conditions are given |U|=14, |(A-B)^(C)|=12, |A cup B|=9 |A triangle B|=7, Where A and B are two subsets of the universal set U and A^(c) represents complement of set A, then

A particle is placed at the origin and a force F=Kx is acting on it (where k is a positive constant). If U_((0))=0 , the graph of U (x) verses x will be (where U is the potential energy function.)

The component forms of vectors u and v are given by u = u = (:5,3:) and v = (:2,-7:) . Given that 2u + (-3v) + w = 0 , what is the component form of w?

The product U is
