An important part of the customer service responsibilities of a
telephone company relate to the speed with which interruptions in
residential service can be repaired on the same day. Suppose that
past data indicate that the likelihood is .54 that interruptions in
residential service can be repaired on the same day. For the first
six interruptions reported on a given day, what is the probability
that:
Solution : Given p = 0.54, n = 6
= > P(X = 6) = 6C6*0.54^6*0.46^0 = 0.0248
Binomial distribution = P(X = r) = nCr*p^r*q^(n-r)
