Answer

Explanation:

Step1: Recall probability formula

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$.

Step2: Identify values

The number of people whose blood - pressure did not change is 57 (favorable outcomes), and the total number of people tested is 300 (total outcomes).

Step3: Calculate probability

$P=\frac{57}{300}=\frac{19}{100}$

Answer:

$\frac{19}{100}$
