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 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 verify that n(A cup B) = n(A) +n(B) -n(A cap B)

Let A={x ; x in N ,\ x is a multiple of 3 } and B={x : x in N\ a n d\ x is a multiple of 5 } . Write AnnB

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) .

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

If A = {letters of word ORANGE } and B = { letters of word MANGO} , find n(A) , n(B) , n(A cup B ) and n (A cap B)

n(A)=20, n(B)=18 and n(A cap B)=5 , then n(A cup 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 .

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

{x : 3x-2 le 10 " and " x in N}
