Question 914089: If a particular medical procedure has a 95% success rate for each time it is performed. Find the following:
a) find the probability that for 3 patients, the procedure was performed successfully for all three of them.
b) find the probability that for 4 patients, the procedure did not succeed one or more times.
c) find the probability that a given procedure will succeed, given that neither of the previous two times it was performed it was successful.

p(success) = .95
n = 3
P(x = 3) = binompdf(3, .95 3) = .8574 0r 85.74%
n = 4
P (x = 0) = binompdf(4, .95,0) = .00000625 0r P = .05^4
P(3rd time yes |not successful 1st and 2nd trials) = .05%2A.05%2A.95 = .002375
Or (1/3)binompdf(3, .95,1)
