Since we have the symbol ⋂, we are looking for the intersection of the given sets.
X&={x |x is an odd whole number less than 16}
Y&={2,6,9,10,16}
Let's rewrite the set X as a set of all integers that are odd and less than 16.
X&={1,3,5,7,9,11,13,15}
Y&={2,6,9,10,16}
The intersection of two sets is the set that contains elements that are common in both sets. An element is in the intersection of X and Y if it belongs to X and to Y at the same time.
X&={1,3,5,7, 9,11,13,15}
Y&={2,6, 9,10,16}
X ⋂ Y &={9}
