Math, asked by fabi, 1 year ago

if setA=(x/0 ≤ x ≤ 5) B=(x/2 ≤ x ≤ 4),C=(x/1 ≤ x ≤ 5),D=(x/5 ≤ x ≤ 7)
then find A-B,C-D.


fabi: we have to find A-B,C-D
fabi: i've typed the same,,i.e.,given..
fabi: ok sure
fabi: gopal,,i got the ans..

A = (x/0 ≤ x ≤ 5)
⇒ A = {0, 1, 2, 3, 4, 5}

B=(x/2 ≤ x ≤ 4)
⇒ B = {2, 3, 4}

C=(x/1 ≤ x ≤ 5)
⇒ C = {1, 2, 3, 4, 5}

D=(x/5 ≤ x ≤ 7)
⇒ D = {5, 6, 7}

1. A - B = {0, 1, 2, 3, 4, 5} - {2, 3, 4} = {0, 1 , 5}
2. C - D =  {1, 2, 3, 4, 5} - {5, 6, 7} = {1, 2, 3, 4}
