Let X is a random variable shows the number of components failed. Here X has binomial distribution with parameters as follow:

n = 11,p=0.6

(a)

The probability that 8 component will fail is

P(X = 8) = ( ) (0.6)8(1-0.6)11-8 = 0.1774

(b)

The mean is

\mu=np=11\cdot 0.6=6.6

The standard deviation is

σ = Vnpil-p) = V1 1 . 0.6 . 0.4 = 1.6248

(c)

Something wrong in this part. Probability that 8 component fail out of 11 is less than 0.45 as calculated in part a.
