Show that `A nnB" "=" "A nnB` implies `A" "=" "B`

Show that A nnB = A uuB implies A = B

Show that A nnB = A nnC need not imply B = C .

Show that for any sets A and B, A = (A nnB) uu(A- B ) and A uu(B - A) = (A uuB)

Using properties of sets, show that(i) A uu( A nnB) = A (ii) A nn(Auu B) =A .

A and B are two events such that P(A)" "=" "0. 54 , P(B)" "=" "0. 69 and P(A nnB)" "=" "0. 35 . Find (i) P(AuuB) (ii) P(A^(prime)nnB^(prime)) (iii) P(AnnB^(prime)) (iv) P(BnnA^(prime))

Find sets A, B and C such that A nnB , B nnC and A nnC are nonempty sets and A nnB nnC=varphi .

Find sets A, B and C such that A nnB , B nnC and A nnC are nonempty sets and A nnB nnC=varphi .

For any sets A and B. show that P(A nnB) = P(A)nn P(B)dot

If A and B are two sets such that n(A)=7, n(B)=6and (A nnB)ne phi Then the greatest possible value of n (A Delta B) is
