Question

A local medical malpractice attorney has noticed that every successful malpractice lawsuit in the last year has originated from one of three offices. Office A saw 1213 patients, of which 6 successfully sued for malpractice. Office B saw 852 patients, of which 7 successfully sued for malpractice. The third office, Office C, saw 215 patients and only had 4 successfully sue for malpractice. Assume that patients only went to one of the three doctor’s offices.

Draw a tree diagram detailing which office a patient saw in the first layer, with the second layer detailing whether or not the patient successfully sued for malpractice
