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?

- 0.122
- 0.196

Hint:

**Hint:-** Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Probability(Event) = Favorable Outcomes/Total Outcomes = x/n

## The correct answer is: 0.122

### Solution:- Option A is correct.

After analysis of table given in the question according to the table, 74 orthopedic surgeons indicated that research is their major professional activity.

Since a total of 607 surgeons completed the survey, it follows that the probability that the randomly selected surgeon is an orthopedic surgeon whose indicated major professional activity is research is 74 out of 607,

Options B, C, and D are incorrect and may be the result of finding the probability that

- For option B the randomly selected surgeon is an orthopedic surgeon whose major professional activity is teaching .
- For option C an orthopedic surgeon whose major professional activity is either teaching or research.
- For option D a general surgeon or orthopedic surgeon whose major professional activity is research.

Therefore the correct option is Option A) 0.122

**Note: **

Whenever we encounter a square root while solving an equation, our first attempt should be to somehow remove the square root by squaring both sides and get a simpler equation to solve. Another way to find the value of x which satisfies the equation would be to simply put the values in the options in the equation and check if it is satisfied
