A doctor is studying the relationship between blood pressure and heartbeat abnormalities
in her patients. She tests a random sample of her patients and notes their blood pressures
(high, low, or normal) and their heartbeats (regular or irregular). She finds that:
(i) 14% have high blood pressure.
(ii) 22% have low blood pressure.
(iii) 15% have an irregular heartbeat.
(iv) Of those with an irregular heartbeat, one-third have high blood pressure.
(v) Of those with normal blood pressure, one-eighth have an irregular
heartbeat.
Calculate the portion of the patients selected who have a regular heartbeat and low blood
pressure.
(A) 2%
(B) 5%
(C) 8%
(D) 9%
