Interpreting PDFs

Consider the PDF shown (it may take a second to load!). Which of the following is true?

50 XP

\(x\) is more likely to be less than 10 than to be greater than 10.

\(x\) is more likely to be greater than 10 than to be less than 10.

We cannot tell from the PDF if \(x\) is more likely to be greater than or less than 10.

This is not a valid PDF because it has two peaks.
