Question: Suppose a radioactive source is metered for two hours, during which time the total number of alpha particles counted is 482. What is the probability

Suppose a radioactive source is metered for two hours, during which time the total number of alpha particles counted is 482. What is the probability that exactly three particles will be counted in the next two minutes? Answer the question two ways-first, by defining X to be the number of particles counted in two minutes, and second, by defining X to be the number of particles counted in one minute.
