If `A = {x: x in W, x lt 2}, B= {x: x in N, 1 lt x lt 5}, C= {3,5}`, find: (i) `A xx (B nn C)` (ii) `A xx (B uuC)`

If A ={x:x in R, x lt 5} and B={x:x in R, x gt 4} , find A cap B .

Let A={x : x in Z, 2 le x le 5} and B={x : x in Z, -2 le x lt 4} . Find the following : (i) n(A uu B) (ii) n(A nn B) (iii) n(A-B) (iv) n(B-A)

If A={(1)/(x) : x in N and x lt 8}and B={(1)/(2x):x in N and x le 4} , find : (i) A cup B (ii) A cup B (iii) A-B (iv) B-A

If A ={2x:x in N and 1 le x lt 4}, B= {(x+2): x in N and 2 le x lt 5} } and C = {x:x in N and 4 lt x lt 8} , find : (i) A cap B (ii) A cup B (iii) (A cup B) cap C

If X= {x:x in N and (x-3)(x-2)=0} Y= {x:x in N and x lt 5} "then find X" cup Y.

Express each of the following sts as an interval : (i) A={x:x in R, -4 , lt x lt 0} (ii) B={x:x in R, 0 le x lt 3} (iii) C= {x:x in R, 2 lt x le 6} (iv) D= {x:x in R, -5 le x le 2 } (v) E= {x:x in R, -3 le x lt2) (vi) F={x:x in R, -2, le x lt 0}

If A = {x in R : 0 lt x lt 1} and B = {x in R : -1 lt x lt 1} , then A xx B is the set of all points lying
