If A = `{x | x in B , x le 10}` and B = `{x | x in W , x le 15 and x ` is a multiple of 5 } , then
find `A cup B and A cap B `

If A = {x | x in B , x le 10} and B = {x | x in W , x le 15 and x is a multiple of 5 } , then find n(A) , n(B) , n(A cup B) and n(A cap B)

If A = {x | x in B , x le 10} and B = {x | x in W , x le 15 and x is a multiple of 5 } , then verify that n(A cup B) = n(A) +n(B) -n(A cap B)

If A = {x : x is a multiple of 3} and, B ={x : x is a multiple of 5}, then A-B is

If A = {x in R : 0 lt x lt 4} and B = {x in R : 1 le x le 7} then find A Delta B .

2 le 3x - 4 le 5 find x

Let A = {x : x is a multiple of 3} and B = {x : x is a multiple of 5), then A nn B is given by

If A = {5, 6, 7, 8, 9}, B={x : 3 lt x lt 8 " and " x in W} and C={x:x le 5 " and " x in N} . Find : (i) A cup B and (A cup B) cup C (ii) B cup C and A cup (B cup C) (iii) A cap B and (A cap B) cap C (iv) B cap C and A cap (B cap C) Is (A cup B) cup C = A cup (B cup C) ? Is (A cap B) cap C) = A cap (B cap C) ?

(i) If A={x:x is a multiple of 2, x lt 15} and B= {x:x in N} then find A and B

If A = { x : x = 3n + 2 , n in N , n le 6} B = { x : xis an even number natural number 4 , lt x lt 15 } and C = { x: x = 3n , n in N , n lt 8 } then find (i) A cup B (ii) A cap B (iii) A cap C (iv) B cap C Also find whether the sets A and B : A and C, B and C are disjoint or overlapping sets .

If A = {x : x is an even natural number upto 20 } and B = {x : x is a factor of 18} ,find n (A) , n(B) , n(A cup B) and n (A cap B) Also varify that n(A)+n(B) = n(A cup B ) +n(A cap B) .
