41% of men consider themselves professional baseball fans. You randomly select 10 men and ask each if he considers himself a professional baseball fan. Find the probability that the number who consider themselves baseball fans is
(a) exactly five
P(x = 5) = 10C5*0.41^5*0.59*5 = binompdf(10,0.41,5) = 0.2087...
----------
(b) at least six
P(6<= x <=10) = 1-binomcdf(10,0.41,5) = 0.1834..
-------------
(c) less than four.
P(0<= x <=3) = binomcdf(10,0.41,3) = 0.358....
------
