<PRE><B>Question 835074</B>
A surgical technique is performed on seven patients. You are told there is a 70% chance of success. 
Binomial Problem with n = 7 and p(success) = 0.7
----------------------------------------------------------------------
Find the probability that the surgery is successful for 
(a) exactly five patients::: 7C5*0.7^5*0.3^2 = binompdf(7,0.7,5) = 0.3177
--------------------------------------- 
(b) at least five patients::: 1- binomcdf(7,0.7,4) = 0.6471
----------------------------------------- 
(c) less than five patients:::binomcdf(7,0.7,4)= 0.3529
====================
