Answer

Explanation:

Step1: Recall probability formula

Probability $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$

Step2: Identify values

The number of people with higher blood - pressure is 28 (favorable outcomes), and the total number of people tested is 200 (total number of outcomes).

Step3: Calculate probability

$P=\frac{28}{200}=\frac{7}{50}$

Answer:

$\frac{7}{50}$
