The probability of receiving more than two pieces of junk mail is found by subtracting the probability of receiving 0, 1, or 2 pieces from 1. Using the Poisson distribution formula, this calculation involves the mean (λ = 4.3) and summing the probabilities for 0, 1, and 2 pieces. The correct answer, after performing these calculations, is 0.8026, indicating a high likelihood of receiving more than two pieces of junk mail.
