b)In n P(A)=1,then the set A is……………

A is a non empty set and let*be a binary operation an P(A)the prower set of A defined by X**Y=XcapY for X, YinP(A) (i) Show that A*B=B* A for A, BinP(A)

b)If A is a set with n(A)=m ,then n(P(A)) =……………

If P(A)=1/2 , P(B)=0 , then P(A | B) is A)0 B) 1/2 C)not defined D)1

If A and B are two events of a random experiment such that P(A)=1/4, P(B)=1/2 and P(A and B)=1/8,then find P(A or B) and P(not A and not B).

If A={a,b,c} , then write power set of P(A) .

If A and B are two disjoint sets,with n(A)=4 and n(B)=2 ,then n(A-B) =……..

If P={-1,1} ,form the set PxxPxxP .
