Explanation / Answer

a. P(0) = exp(-87/280) = 0.7329

Now , for the second problem

a. P(0) = exp(-73/280) = 0.7705

b. P(1) = ( exp(-73/280) * (73/280)1 ) / 1! = 0.2009

c. P(2) = ( exp(-73/280) * (73/280)2 ) / 2! = 0.0262

d. P(3) = ( exp(-73/280) * (73/280)3 ) / 3! = 0.00227

e. P(4) = ( exp(-73/280) * (73/280)4 ) / 4! = 0.0001
