The FAA, being data-driven, came to the same conclusion: there is four masks per row of three, plus a couple extra in the toilet, so if 25% don't work everyone should still have a working mask, statistically speaking. Really don't see what the problem you people have.
Oh, the whole row wouldn't work if the valve doesn't open....
