Answer:
Correct option is
C) 1500 people per event
Explanation:
To find the rate, you will need to first divide the number of casualties by the number of events needed to produce an impact.
I.e Number of casualties / Number of events needed to produce an impact
= 30,000,000/21000 =
30000/21= 1429
Since 1429 is approximately 1500, it is the closest to the answer than any other option.
The correct answer is 1500 people per event.
