Side Note: What does it mean to be published? I'd always been told that the Gutenberg's Bible was the first book published. I knew this wasn't true because even Gutenberg used his printing press to produce other books before he printed the Bible. However, I have always considered the Gutenberg Bible as published, because he did use a printing press to produce 180 of them. So, what is the actual criteria for "published"?

N E W Q U I Z ! ! !
Only 3% of Americans got this question correct on the Yale Law Quiz mentioned above.
Suppose you have a close friend who has a lump in her breast and must have a mammogram. Of 100 women like her, 10 of them actually have a malignant tumor and 90 of them do not. Of the 10 women who actually have a tumor, the mammogram indicates correctly that 9 of them have a tumor and indicates incorrectly that 1 of them does not have a tumor. Of the 90 women who do not have a tumor, the mammogram indicates correctly that 81 of them do not have a tumor and indicates incorrectly that 9 of them do have a tumor. The table below summarizes all of this information. Imagine that your friend tests positive (as if she had a tumor), what is the likelihood that she actually has a tumor?
