If `A` and `B` are two sets then prove that `(AuuB)'uu(A'nnB)=A'`

If A and B are two sets then prove A = A nn(A uu B).

If A and B are any two sets, then prove that (A nn B) uu (A-B)=A

If A and B are two independent events, prove that P(AuuB).P(A'nnB')<=P(C) , where C is an event defined that exactly one of A and B occurs.

If A and B are two independent events, prove that P(AuuB).P(A'nnB')<=P(C) , where C is an event defined that exactly one of A and B occurs.

If A and B are two sets, then A nn (A uu B) equals

If A and B are two sets, then A nn (A uu B) equals

If A and B are two sets ,then (A-B)uu(B-A)uu(AnnB) equals

For any two sets, prove that: \ Ann(AuuB)=A

If A, B are two sets, prove that AuuB=(A-B)uu(B-A)uu(AnnB) . Hence or otherwise prove that n(AuuB)=n(A)+n(B)-n(AnnB) where, n(A) denotes the number of elements in A.

If A and B are two events such that P(AnnB)=0.3 and P(A'nnB')=0.6 , then the value of P(AnnB' or A'nnB) is equal to
