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}
