When studying radioactive material, a nuclear engineer found that over 365 days, 1,000,000 radioactive atoms decayed...

When studying radioactive material, a nuclear engineer found that over 365 days, 1,000,000 radioactive atoms decayed to 973,846 radioactive atoms, so 26,154 atoms decayed during 365 days.

a. Find the mean number of radioactive atoms that decayed in a day.

b. Find the probability that on a given day, 51 radioactive atoms decayed.
