Typo repairs in Flashcards

I’ve just finished fixing typos in a couple of flashcards.   The first three are in C.2, cards 22-24.  These say H_0, when they should have H_1 as in the summary sheet.

Also, on D.3, the fomula with the negative binoimal deviance should have a negative sign, as in the formula sheet, and now it does!

Happy last week of studying!
