Oct 30 at 12:36 comment added PM 2Ring @David Sure. My comment is just a warning to the OP (& other interested readers) that there are other neutrinos to consider in a supernova.
Oct 30 at 12:32 comment added David Hammen @PM2Ring Yes, the question is a bit artificial. So? Lots of introductory level questions in the sciences might as well start with "assume a spherical cow ..."

Oct 30 at 11:22 comment added PM 2Ring The info in the problem statement appears to neglect the huge numbers of thermal neutrinos (and antineutrinos), and only considers the neutrinos released when protons convert to neutrons. So it's a rather artificial problem. For info on the thermal neutrinos, please see astronomy.stackexchange.com/q/57832/16685 & links therein.
