Here's your shmoop du jour...

00:05

At Hogwarts, there's a raging debate about whether there are more witches or wizards on the premises.

00:11

The breakdown of the number of female and male students and faculty members

00:14

is shown below in the table.

00:16

Which of the following pie charts correctly represents the data given in the table?

00:20

And here are the potential answers...

00:28

The question is just asking us to take a percentage of the numbers given.

00:31

Let's start with female students.

00:33

First of all, we can sum up ALL the witches and wizards to get our total population...

00:39

475 + 425 + 35 + 25 equals 960.

00:46

475 out of 960 are female students, so we divide to get a percentage.

00:53

475 divided by 960 is about 49 percent...

00:59

...and there's only one chart that matches up.

01:01

We can double-check by running numbers on the male students, female faculty or male faculty...

01:07

...but honestly, we already have our answer, and life's too short.

01:10

These tests are timed, and you gotta wave your wand when you can.

01:13

Our answer is choice A.

01:15

As in... "'arry Potta'!"
