Example Question #10 : How To Find The Answer From A Table

Graph

The above circle graph shows the results of a school election. According to the rules, the election falls to the student who wins the majority of the votes; if no student wins a majority, the top two vote-getters will face each other in a runoff, with the winner being elected.

Which of the following is the result of this election?

Possible Answers:

Phelps, Creighton, and Wells will face one another in a runoff.

Phelps and Wells will face each other in a runoff.

None of the other choices is correct.

Phelps won the election outright.

Phelps and Creighton will face each other in a runoff.

Correct answer:

Phelps and Creighton will face each other in a runoff.

Explanation:

Since each of the six portions of the graph takes up less than half, no one won a majority. Therefore, there will be a runoff. The two largest portions are light blue (Phelps) and orange (Creighton), so Phelps and Creighton got the most and second-most votes, and they will face each other in a runoff.

Example Question #132 : Probability

Use the following table to answer the question.

Table2

How many students received an A in math?

Possible Answers:

Correct answer:

Explanation:

When looking at the table

Table2

we can see that is shows several students and within the subjects of Math, Science, and Art what grades those students received in those classes.

So, going over the table briefly, we can see the first student Katrina.  We see for Math she received an A.  For science, Katrina received an A.  And for Art, Katrina got a B.  We can read the table similarly for the remaining students.

Now, the question asks how many students received an A in math.  So we will look through the table and locate Math.  Once we locate Math, we will look at the grade that corresponds with it (In this example, we do not care about who the student is.  We just care about the grade).  So, we will count the number of A's we see matched up to the subject Math.

Once we do that, we see there are 3 students who received A's in Math (Katrina, Chris, and Fionn).
