(x + y)(x + 5y) = x² + 6xy + 5y², not in the given form.
(x + y)(x - y) = x² - y², this is one of the possibilities.
(x + y)(5x - y) = 5x² + 4xy - y², not in the given form.
(x + 5y)(x - y) = x² + 4xy - 5y², not in the given form.
(x + 5y)(5x - y) = 5x² + 24xy - 5y², not in the given form.
(x - y)(5x - y) = 5x² - 6xy + y², not in the given form.

Therefore, required probability = [spoiler]1/6[/spoiler]

The correct answer is E.
