A logistics operations analyst investigates parcels for two specific errors: Delayed Shipping ( $D$ ) and Mislabeled Address ( $M$ ). The probability that a parcel is delayed is 0.15. If a parcel is delayed, the probability that it is also mislabeled is 0.20. If a parcel is not delayed, the probability that it is mislabeled is 0.06.

Construct a tree diagram to represent this information, including all branch probabilities for $D$ and $M$ .

Find the probability that a randomly selected parcel has exactly one of these two errors: Delayed Shipping or a Mislabeled Address.

The analyst also notes that a parcel can suffer External Damage ( $E$ ) with a probability of 0.10, and this flaw is independent of shipping delays or labeling errors.

Determine the probability that a randomly selected parcel has none of these three flaws.

Calculate the probability that a randomly selected parcel has exactly one of these three flaws.
