Answer 1

Answer: D. 0.322

Step-by-step explanation:

Given : Of 1232 people who came into a blood bank to give​ blood, 397 people had high blood pressure.

Then, the probability that the next person who comes in to give blood will have high blood pressure will be :_

$\dfrac{\text{People had high blood pressure}}{\text{Total people}}\\\\=\dfrac{397}{1232}\\\\=0.32224025974\approx0.322$

Hence, the estimated probability that the next person who comes in to give blood will have high blood pressure = 0.322

Answer 2

The answer is D
397/1232=0.322
