Per current schools question and answer requested students to state what they agree to is the main important element for a student to do if they wanted to hit success. A lot of comments, the one that that stood out was practice. Successful persons are not born successful; they become successful by just hard work and dedication. If you wish to fulfill your goals, keep this in mind! These are are one of the answer and question example that you can potentially make use of to practice and supercharge your knowledge and also give you insights that could just help you to keep up your study in school.

## Question:

Sam is testing the effectiveness of a new cough medication. There are 100 people with a cough in the study. Thirty patients received the cough medication, and 70 other

patients did not receive treatment. Seventeen of the patients who received the medication reported no cough at the end of the study. Twenty-eight of the patients who did

not receive medication reported no cough at the end of the study. What is the probability that a patient chosen at random from this study took the medication, given that

they reported no cough?

## Answer:

The **probability** that a patient **chosen** at random from this **study** took the medication, given that they reported **no cough** should be **38%.**

### Calculation of the probability:

** Took medication Didn’t take medication Total**

No cough 17 28 45

Cough 13 42 55

Total 30 70 100

Now the probability be

= 17/45

= 37.777

= 38%

From the answer and question examples above, hopefully, they can potentially guide the student resolve the question they had been looking for and take note of everything that declared in the answer above. You will be able to then have a discussion with your classmate and continue the school learning by studying the subject to one another.
