Answer:
<u>There are 300 chapter books and 200 picture books in the children's section at the local library.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Number of books in the children's section at the local library = 500
Ratio 2:3 for picture books and chapter books
2. How many chapter books are in the section?
We will use the Rule of Three Simple for answering this question, this way:
Chapter books Total books
3 5
x 500
x * 5 = 500 * 3
5x = 1,500
x = 1,500/5
x = 300
<u>There are 300 chapter books and 200 picture books in the children's section at the local library.</u>
Right off the bat (haha), we can eliminate B as an answer choice because adults are clearly part of the population; in fact, it says in the background information that their entire population is made of adults. A population, in this context, is the group being researched.
D isn't the correct answer; the fact that adults are the target population doesn't validify anything.
C doesn't entirely prove its point because there are other factors that go into the game being biased. In fact, I would say that this study <em>is </em>biased because the board members only attended 1 game when there are 18 teams. Their data will only pertain to fans of the 2 teams playing each other, and not represent the population as a whole.
A would be my answer for reasons stated above.

Total juice boxes = 3 + 1 + 2 + 4 = 10
probability first one out is grape = 2 / 10
probablility second one out is grape 1 / 9 (one taken already and only nine left)
