We spent a good 30 minutes talking about how if the probability of something happenining ( P(e) ) is subtracted from one it will equal the odds of it not happening...
1- P(E) = odds of P(E')
After that, the rest of the class was spent arguing whether or not occur would have an "s" in how he wrote it out. Easily 20 minutes over one stupid word that had nothign to do with math.
Wow. Grammar fight in Math class.
Never thought I'd see the day.
Good thing I had blank paper to draw on.
