19. Carlson Jewelers permits the return of their diamond wedding rings, provided the return occurs within four weeks of the purchase date. Their records reveal that customers return 20% of the diamond wedding rings. Five different customers buy a wedding ring. What is the probability that either one or two customer of the five customers return a ring?
