Brilliant Student Puzzle

Brilliant Student Puzzle Solution - 18 November

There was once a college that offered a class on probability applied to the real world.The class was relatively easy, but there was a catch. There were no homework assignments or tests, but there was a final exam that would have only one question on it.When everyone received the test it was a blank sheet of paper with a solitary question on it: 'What is risk?'.Most students were able to pass, but only one student received 100% for the class! Even stranger was that he only wrote down one word!
What did he write?

Solution
the brilliant student wrote down:

"This."

And handed in the paper.

By doing this, the student demonstrated that he understood that having your grade based on one exam is risky.
Plus, putting just one word on such an important exam and hoping the professor understands what he means is risky in and of itself!
