Quiz: If the odds of me accepting feature X is x% and the odds of me
accepting feature Y is y%, what are the odds of me accepting both in one
patch?

a) max(x, y)
b) min(x, y)
c) x * y / 100
d) 0

If you know your probability, you might suspect the answer is (c), which
is always less than min(x, y): you're always decreasing your odds of
acceptance by combining. But if you know me, you'll realize the answer
is actually zero, because I reject such patches on principle.
