Ms. Johnston, Ms. Johnson, and Ms. Johnstone all entered the same hospital and gave birth to baby girls on the same day, and all three babies were taken to the nursery to receive care, there. Someone later claimed that the hospital mixed up the babies. As a hospital administrator, it is your job to make sure that each pair of parents has the correct baby, so you order blood typing to be done on all the parents and all the babies. Here are the results: Ms. Johnston A+ and Mr. Johnston B+; Ms. Johnson B- and Mr. Johnson O+, Ms. Johnstone A+ and Mr. Johnstone A-; Baby 1= O-, Baby 2 = AB -, and Baby 3 = B-. Match the babies with the parents.
