Oh no! A trolley is heading towards two infinite tracks of people. If you do nothing the trolley will stay on track where it'll kill people lying in an infinite sequence of equidistant ones (1 1 1 1 1 1 .... 1 ....), but if you pull the leaver it will go to the other infinite track killing people laying in equidistant piles corresponding to ordinal (1 2 3 4 5 .... (n) ...). What to do? Pull the lever -- you'll only kill -1/12 people instead of infinity.
