11.1 #15

Answer 1

0.0001

Explanation:

The empirical probability is the ratio of the number of times a particular event occurs relative to the total number events. In this case, it is how many babies were born with a syndrome relative to the sample total.

There are 70,000 first born babies, and 7 with the syndrome. Therefore, the probability is:

7/70,000 = 1/10,000 = 0.0001
