I'm going to round these numbers to make them easier to work with. We will get an approximate answer.
<span>350 / 2000 </span>
<span>= 35 / 200 </span>
<span>= 3.5 / 20 </span>
<span>= 0.35 / 2 </span>

<h2>Answer:</h2>

Probability that the next person who comes in to give blood will have high blood pressure is:

0.3222

<h2>Step-by-step explanation:</h2>

Let A be an event

then, P(A)= number of favorable events/total number of events

Here, A: People having high blood pressure

P(A)= number of people having high blood pressure/total number of people

= 397/1232

= 0.3222

Hence, probability that the next person who comes in to give blood will have high blood pressure is:

0.3222
