I am very bad at mathematics, so apologies in advance. My confusion comes from the voting system on an online poll. Example video (Picked at random): http://www.funnyordie.com/videos/4d0ac00700/youre-pitiful-weird-al-yankovic-ver-1-from-insane_ian

The percentage is 71%, meaning that some combination of "funny" or "die" votes added up to that. If 10 out of 100 people voted "funny" it would be easy to say that the percentage who thought it was funny is 10%, I am wondering how the number is derived taking both into account.

Hopefully I worded this correctly. I have a feeling it is something simple that I just don't remember. Thanks. I'm not sure what to tag this with, so I'm taking my best guess. Sorry if that's wrong.

    Sorry about the ambiguity, but if you view the site and look below the video you will see the voting options and the percentage in the middle. Flash player might be required.2012-06-22

There are four possibilities. You might make a Venn diagram. Each voter has said funny or not funny, and die or not die [is it required that they vote on both?]. We are told that (funny and die) + (funny and not die) + (not funny and die) is 71%, so (not funny and not die) is 29%. If you want to separate funny and die, you need more data. In your example, if funny is 10%, die might be 71% (if all the funnys are also die) or 61% (if none of the funnys are also dies).
