Question

If A={2,3,4,5), B={4,5,6} and C={6,7}
then A-(BUC) =......
{2,3)
O {2,3,4,5)
O {2,3,6,7)
OO)​

Answer 1

Answer:

{2,3}

Step-by-step explanation:

(BUC)={4,5,6,7}

A-(BUC)={2,3,4,5} - {4,5,6,7}= {2,3}

Answer 2

Step-by-step explanation:

(BUC)=(4,5,6)U(6,7)

=(4,5,6,7)

A=(2,3,4,5)

then A-(BUC)= (2,3,4,5)-(4,5,6,7)

=(2,3). answer
