You can put this solution on YOUR website! 31% of adults would pay more for environmentally friendly products. You randomly select 10 adults.
Binomial problem with n = 10 and p = 0.31
--------------------------------------------
Find th eprobability that the number of adults who would pay more for environmentally friendly products is
(a) exactly two,; binompdf(10,0.31,2) = 0.2222
(b) more than two ;1 - binomcdf(10,0.31,1) = 0.8656
(c) between two and five, inclusive::
binomcdf(10,0.31,5)-binomcdf(10,0.31,1) = 0.8105
