Question

According to the following results, what is the probability that a person taking this drug will experience a loss of sleep?

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.)

Answer 1

`6%`

Explanation:

Since we have `100` people we don't need to do any further calculations, because the number will be equal to the percentage (remember `%` is how much/many out of `100`), if that makes sense.

By reading the question, we can see that `6` patients reported a experiencing a loss of sleep.

Therefore we have `6` people out of `100`. Therefore, as mentioned above, that is equal to `6%`.
