Counting Principle, a la Shmoop. Dagun-Ra, Lord High Chancellor of the Volcano
00:12
people, is in a pickle.
00:16
It is Dagun-Ra's duty to choose those who will be sacrificed to Mount Lascivious.
00:23
But he's so bad at making decisions. He must choose to sacrifice one of the town's
00:34
goats, Alfred, Bobo or Chewy…

00:40
…one of the town's donkeys, Darius, Eeyore or Fartsy…
00:48
…and one of the town's lawyers, Geoff, Harper, Irving or Jarvis.
00:56
He briefly considers just tossing in all of the lawyers, but he doesn't want to upset
01:08
the Volcano god. How many different combinations does Dagun-Ra
01:13
have to choose from?
01:15
Here are your options: First things first - we need to count up the
01:23
number of options for each category.
01:26
Looks like we're working with three goats…
01:28
…three donkeys…
01:29
…and four lawyers. To find the total number of combinations,
01:33
we would simply multiply those three numbers together.
01:36
Three times three times four equals… 36. Answer "E."
01:50
It takes him a while, but Dagun-Ra finally narrows his list of 36 possibilities down
02:23
to one.
02:26
Into the volcano go Chewy, Fartsy and Jarvis.
02:31
For at least another year, the volcano should have no further need for animal or human sacrifice.
02:45
Or for free legal advice.
