When studying radioactivematerial, a nuclear engineer found that over 365days, 1,000,000 radioactive atoms decayed to 971,938 radioactiveatoms, so 28,062 atoms decayed during 365 days.

a. Find the mean number of radioactive atoms that decayed in a day. (Round to three decimal places asneeded.)

b. Find the probability that on a givenday, 51 radioactive atoms decayed. (Round to six decimal places asneeded.)
