All 12 months have at least 28 days. February has exactly 28 days (29 in leap years), while all other months have more than 28 days.

There are only 2 intervals between 3 pills, so 2 × 30 = 60 minutes.

The phrase 'all but 9 die' means that every sheep except 9 dies. So 9 sheep remain alive, not 8. Many people mistakenly subtract 9 from 17.
