Question

Let D= {4,7,9} , let E {4,6,7,8}, and let F={3,5,6,7,9}a) find the D U Eb) find the E n F

Answer 1

the given sets are,

D= {4,7,9} , let E {4,6,7,8}, and let F={3,5,6,7,9}

now,

D U E = { 4 , 6, 7 , 8, 9}

and'

E intersection F = E n F = {6 , 7)

thus, the answer is

D U E = { 4 , 6, 7 , 8, 9} and

E n F = {6 , 7)
