Question

the chance of getting a rare disease is .03 per person. out of 1,000 people, how many of them are expected to get the disease?

Answer 1

I believe the answer would be 30 people.

Explanation:

To calculate the percentage out of a group of people or items, you just multiply the percent (in decimal form) by the amount of people you want it out of. For example: A 0.1% chance out of 1,000 people would be a chance and expectancy of 1 person out of those 1,000 people. In this case it's 3% for every person. 0.03 • 1,000 is 30.
