Suppose that the probability of electricity failure in a given month in Yuen Long is 2%. The district manager of the China Light & Power Co., Lid wants to know the probability that Yuen Long can go a number of months free from electricity failures before experiencing the first failure. Let X = the number of months required to have the first failure. (a) Suggest a suitable probability distribution for this situation. [2] (b) Compute P(X > 2). [2]
