A:
To get the percentage of patients with AB blood type, divide the number of patients with AB blood type by the total number of patients and then multiply the quotient by 100 to get the percentage as follows: Total number of patients with AB blood type = 33 patient Total number of patients = 714 patient
% of patients with AB blood type = (33/714) * 100 = 4.6%
