------
Binomial Problems with p(defective) = 3/250 ; p(good) = 247/250
---------------------------
Determine how many ways, and the probability, a vending company can buy three of these units and receive
(a) no defective units.
# of ways:: 247C3 = 2481115 ways
----
P(no defect) = 247C3/250C3 = 0.9643
---------------------------------
(b) all defective units.
# of ways:: 3C3 = 1
P(3 defective) = 1/250C3
----------------------------------
(c) at least one good unit.
# of total ways - # of ways with no defects = 250C3-247C3 = 91885
P(at least one defect) = 91885/250C3 = 0.0357
