Question

In a survey, 607 general surgeons and orthopedic surgeons indicated their major professional activity. The results are summarized in the table above. If one of the surgeons is selected at random, which of the following is closest to the probability that the selected surgeon is an orthopedic surgeon whose indicated professional activity is research?

Answer 1

To find the probability, we divide the number of orthopedic surgeons whose indicated professional activity is research by the total number of surgeons.

Step-by-step explanation:

To find the probability that the selected surgeon is an orthopedic surgeon whose indicated professional activity is research, we need to consider the given table:
Professional Activity
General Surgeon
Orthopedic Surgeon

Clinical Practice
370
270

Research
110
220


Teaching
120
210

The probability can be calculated by dividing the number of orthopedic surgeons whose indicated professional activity is research (220) by the total number of surgeons (607). So, the probability is approximately 220/607 which is approximately 0.362 or 36.2%.

Answer 2

Choice A would be correct.
