Patients with an age less than or equal to 50; with tcV level greater than 3.5; receive 3.0mg of the medicine. Patients with age less than or equal to 70; regardless of tcV levels; receives no medicine. If one were to develop a decision tree for testing this program, how many test cases would be needed?
