# According to the following results, what is the probability that a person taking this drug will experience a rise in blood pressure?

## A drug was administered to 100 people. Follow-up interviews were conducted in which patients were asked whether or not they experienced various side effects. 7 of the patients reported experiencing a rise in blood pressure, 6 of the patients reported experiencing a loss of sleep, and 3 reported experiencing both of these side effects. (i.e. A total of 7 patients said yes when asked whether they experienced a rise in blood pressure, a total of 6 said yes when asked whether they experienced a loss of sleep, and a total of 3 said yes in both cases.)

10%

#### Explanation:

We know that seven patients reported a rise in blood pressure and another three reported BOTH an increase in blood pressure and loss of sleep.

So the total amount of patients who experience some type of rise in blood pressure is $10$

We are also given the information that this was conduct on a survey group of $100$.

So, now we can see that for every $100$ people surveyed at least $10$ of those might see a rise in blood pressure.

Or

$\frac{10}{100} = .10$

.10xx100=10%

• 10/100=10%

#### Explanation:

• 6 people had sleep loss among that 3 had both Bp and sleep loss

• among these 3 had sleep loss and 3 had Bp .

So 7+3=10.
