Question

20 POINTSSS HELPLet X and Y be the following sets:X = {5, 10, 15)Y = {3, 6, 9, 12, 15}Which of the following is the set XUY?

Answer 1

The initial sets are:

`\begin{gathered} X=\mleft\lbrace5,10,15\mright\rbrace \\ Y=\mleft\lbrace3,6,9,12,15\mright\rbrace \end{gathered}`

So the union between them we combinate the items:

`\text{XUY}=\mleft\lbrace3,5,6,9,10,12,15\mright\rbrace`
