6. There are four QA inspectors in a packaging factory. Each one is supposed to stamp the date of arrival on each package at the end of the line. James, who stamps 20% of the packages, fails to stamp the expiration date once in every 200 packages; Jessie, who stamps 60% of the packages, fails to stamp the expiration date once in every 100 packages. Leah, who stamps 15% of the packages, fails to stamp the expiration date once in every 100 packages; and Andre, who stamps 5% of the packages, fails to stamp the expiration date once in every 200 packages. If a customer complains that the date of arrival was not stamped on, what is the probability that it was inspected by Jessie?
