Question

A={odd numbers x less than 10}
B={X:X=2^N+1/2 N=0,1,2,3}
C={X:X£n;and x is not equal to 5}
Find A-B,AuB,AnB,Au(Buc) with ven diagrame​

Answer 1

A = { 1,3,5,7,9}

B = { 1,3/2,5/2,9/2}

C = { 1,2,3,4 }

A - B = {3,5,7,9}

A n B = {1}

A u B = {1,3,5,7,9,3/2,5/2,7/2,9/2}

A u (B u C) = {1,3,5,7,9,3/2,5/2,7/2,9/2,2,4}
