the sets A= {x: 1<=x<=3} and B = {x: x= 1,10} are subsets of U = {x:1<=x<=10}, where X is an integer. (a) list the members of the sets A,B and U (b) Find A n B

Question

A={x:1}<=x<={3}

Answer 1

the sets A= {x: 1<=x<=3} and B = {x: x= 1,10} are subsets of U = {x:1<=x<=10}, where X is an integer. (a) list the members of the sets A,B and U (b) Find A n B

A = {z: 1 <= x <= 3}    this gives A = {1, 2, 3}

B = {x: 1, 10}              this gives B = {1, 10}

U = {x: 1 <= x <= 10}  this gives U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

b) A n B = {1, 2, 3}​ n {1, 10}​ = {1}
