Question

The probability that a person drinks at least five cups of coffee per day is 0.24, and the probability that a person has high blood pressure is 0.16. Assuming that these two events are independent, find the probability (to four decimal places) that a person selected at random drinks less than five cups of coffee per day and has high blood pressure.

Answer 1

Solution

Step 1:

Given data

The probability that a person drinks at least five cups of coffee per day = 0.24

The probability that a person has high blood pressure = 0.16

Step 2:

The probability that a person selected at random drinks less than five cups of coffee per day and has high blood pressure

$\begin{gathered} =\text{ 0.24 }\times\text{ 0.16} \\ \text{= 0.0384} \end{gathered}$

Final answer

0.0384
