a. Suppose two customers are to be selected at random. Would it be reasonable to consider the events C₁ = event that the first customer selected subscribes to cable TV and C₂ = event that the second customer selected subscribes to cable TV as independent events? Explain.

b. With C₁ and C₂ as defined in Part (a), calculate P(C₁ ⋂ C₂).
