Phone calls can be classified as voice (V) if someone is speaking, or data (D) if there is a modem or fax transmission. Based on many observations made by the telephone company, we have the following probability model: P [V] = 0.8, P [D] = 0.2. Data calls and voice calls are produced independently. The random variable Kn is the number of data calls in a collection of n calls telephone (a) What is the E [K100], the expected number...
