What is the probability that —
(i) No car will be brought back P(none) = (0.80)^10 = 0.1074
------------------------
(ii) Exactly two cars will be brought back.
P(x=2) = binompdf(10,0.2,2) = 0.3020
------------------------
(iii) At least two cars will be brought back.
P(2 <= x <= 10) = 1 - binomcdf(10,0.2,1) = 0.6242
------------------------
