Fail!
Thank you to all who caught our mistake, now corrected, on “Yippee!”, our Math Beast problem for the week of 10/17/11. As the posted explanation revealed, both Quantities were intended to have a factorial in both numerator and denominator. However, the posted question was missing that crucial exclamation point in the numerator of Quantity B, an omission that affected the answer. The error occurred for the most mundane of reasons: fancy fractions and figures must be created separately and posted as image files, not a simple cut-and-paste. We regret that we lost the “!” during image creation, and apologize for any consternation this may have caused. Thanks for keeping us on our toes! <-- Exclamation point pun intended.
