I'm going to round these numbers to make them easier to work with. We will get an approximate answer. 
350 / 2000 
= 35 / 200 
= 3.5 / 20 
= 0.35 / 2 
= 0.175 

answer is 0.175

Answer:

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

0.3222

Step-by-step explanation:

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
