American Housing Survey for the United States. From that document

American Housing Survey for the United States. From that document, we found that 1.4% of occupied housing units have seven or more people living within. Use the Poisson distribute to determine the approximate probability that, of 200 randomly selected occupied housing units, there are:

(a) none with seven or more persons.

(b) three or more with seven or more persons          

(c) Differentiate between the binomial and the Poisson distributions
