Question

Select the statements that are true based on the following given information.
D = {x | x is a whole number}
E = {x | x is a perfect square < 36}
F = {x | x is an even number between 20 and 30}

The expression D ∪ E = E.
E ∪ (D ∩ F) is {25}.
F ⊂ D
(E ∩ F) is the empty set.
Set E is infinite.
