I believe that four engines are safer at any p failure less than one third (which is VERY unreliable). Thus for any reasonable failure rate four engines are better than two. BTW I am dreging this up from my recollection of a statistics course many years ago so if anyone else remembers this problem feel free to comfirm or dispute. All the usual disclaimers.
