Question

Perform the given set operation. Let
U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}.

(Enter your answers as a comma-separated list. Enter EMPTY for the empty set.)

{x | x is a multiple of 2} ∪ {x is a multiple of 7}

Answer 1

the first set would be {2,4,6,8,10}
the second set would be {7}

so {2,4,6,8,10} ∪ {7)
= { 2,4,6,7,8,10}
