Answer
XUY = {1, 2, 3, 5, 6, 7, 9, 10, 11, 13, 15, 16}
Work Step by Step
X= {x | x is an odd whole number less than 16}
Y = {2, 6, 9, 10, 16}
We are looking for the union of the two sets, so any element in either set is in the union.
X= {1, 3, 5, 7, 9, 11, 13, 15}
Y = {2, 6, 9, 10, 16}
XUY = {1, 2, 3, 5, 6, 7, 9, 10, 11, 13, 15, 16}
