You can put this solution on YOUR website! A man sends four application forms to apply for shares in company V,W, and Z. if the probability of each form being successful is 3/5. find the probability that he is successful in
a)P(at least 3 applications) = 1-P(0<= x <=2) = 1-binomcdf(4,3/5,2) = 0.4752
--------------
b)P(less than 3 applications) = P(0<= x <=2) = 1-0.4752 = 0.5248
