Given:

Let X and Y be two sets.

The two sets are given by X=\{5,10,15\} and Y=\{3,6,9,12,15\}

We need to determine the value of the set X \cup Y

Value of the set X \cup Y:

The value of the set X \cup Y is the set that contains all the elements that are at least in one of the two sets.

Hence, the union of the set X \cup Y is given by

X \cup Y=\{5,10,15\} \cup \{3,6,9,12,15\}

X \cup Y=\{5,10,15,3,6,9,12\}

Arranging in ascending order, we get;

X \cup Y=\{3,5,6,9,10,12,15\}

Thus, the union of the sets X and Y is X \cup Y=\{3,5,6,9,10,12,15\}
