Question 702770
A new surgical operation procedure is said to be successful 85% of the time. If the procedure is performed on 8 patients independently, what is the probability that at least 6 operations are successful? 
----
Binomial Problem with n = 8 ; p(success) = 0.85
----
P(6<= x <=8) = 1-P(x<= 5) = 1 - binomcdf(8,0.85,5) = 0.8948
Cheers,
