Question 1198209
p(fail the first hour of operation ) = .01
Sample 100 computers:
n =100
The mean = np = 100(.01) = 1, simply the MEAN number of computers 0r expected number that will fail out of 100.
That exactly ONE WILL fail...probability of that happening would need to be a  p = 1
I. Using a Binomial Distribution: p = .01 and n = 100
Using TI or similarly an inexpensive calculator like an Casio fx-115 ES plus
P(x=1) = binompdf(100, .01) = .3697
II. Using a Poisson Distribution approximation to the Binomial Distribution::
P(x = 1) = .3679
III. That exactly ONE WILL fail? 
Can happen, WILL it happen?? probably not.  FAlse is Your answer.
