The article “Doctors Misdiagnose More Women, Blacks” (San Luis Obispo Tribune, April 20, 2000) gave the following information, which is based on a large study of more than 10,000 patients treated in emergency rooms in the eastern and midwestern United States:

1. Doctors misdiagnosed heart attacks in 2.1% of all patients.

2. Doctors misdiagnosed heart attacks in 4.3% of black patients.

3. Doctors misdiagnosed heart attacks in 7% of women under 55 years old.

Use the following event definitions:

M = event that a heart attack is misdiagnosed,

B = event that a patient is black, and

W = event that a patient is a woman under 55 years old.

Translate each of the three given statements into probability notation.
