XUY is the false statement.
Step-by-step explanation:
Given X = {15, 22, 33, 44, 89, 165, 1025}
and Y = {-5, 15, 33, 88, 99, 150, 160, 1025}
1). XUY = All elements or terms of both the sets.
XUY = {-5, 15, 22, 33, 44, 88, 89, 99, 150, 160, 165, 1025}
But the in the given option 88 is missing. Therefore, this statement is False.
2). X∩Y = common terms of both the sets.
X∩Y = {15, 33, 1025}
Matches the given option, so true.
3). ∅ ⊂ (XUY)
Since empty set is a subset of every set so this option is also true.
Therefore, XUY is the false statement.
