A mail-order firm considers three possible foul-ups in filling an order:A: The wrong item is sent.B: The item is lost in transit.C: The item is damaged in transit.Assume that event A is independent of both B and C and that events B and C are mutually exclusive. The individual event probabilities are P(A) = 0.02, P(B) = 0.01, and P(C) = 0.04. Find the probability that at least one of these foul-ups occurs for a randomly chosen order
