[math-fun] Possibility puzzle

Apparently, possibility is the intersection of probability with Boolean algebra. A certain 4th grade teacher decided to enrich Saxon Math with a few days of re-education from a private copy of something called "Logic Liftoff", followed by a test supposedly copied therefrom, on which a certain confused 4th grader apparently was reduced to bluffing with ambigrams: gosper.org/logic.png <http://gosper.org/logic.png>. I don't understand how he got credit on the first five answers, since their correct answers are clearly "the sun will rise tomorrow." Or how he didn't lose 5 more points for "Febuary". I actually had to Google for reassurance that they weren't dumbing down the spelling. --rwg
