Question

If u={1,2,3,4,5,6,7,8,9,10},A={x:xgreater thanor equal to 4} and B={x:X<8} find A intersectionB and A-B

Answer 1

Answer:⤵️

AnB = {4,5,6}

A-B = {8,9,10}

Step-by-step explanation:⤵️

U={1,2,3,4,5,6,7,8,9,10}

A={x:x>_ 4} = {4,5,6,7,8,9,10}

B={x:x<8} = {1,2,3,4,5,6,7}

then,

AnB

={4,5,6,7}

A-B

= {8,9,10}
