# With Great Food Comes Great Responsibility

(6)
Tuition given in the topic of Miss Loi's Temple aka Joss Sticks Tuition Centre from the desk of at 7:48 pm (Singapore time)

Since the earlier post on the gastronomical delights that await students at The Temple, there seems to be some dissent coming from a minority (read: minority) section of the student population:

How come only have Mentos and Fruit Plus?! Where are the marshmallows and Galatine chocolate you promised on your blog?! I don’t care! I want my money back!!!

Miss Loi you stole ALL MY food!

We want Ferrero Rocher! We want Ferrero Rocher!

Now before you bunch of rowdy radical youths commence your sit-in demonstration outside the hallowed Temple Gates, let Miss Loi remind you of the following para at the end of that post:

… let it be known that these premium tidbits are only available as rewards to those of you who can answer the questions correctly in class!

Yeah that’s right, there’s no free marshmallow in this world!

To facilitate this, Miss Loi shall now indicate in worksheets via (*) asterisks all ‘premium’ questions which, if answered correctly, will lead to a marshmallow/Mallow Blast/Galatine chocolate popping into your mouth.

Only valid if you get it correct on your first attempt on your own. Not counted if there’s any assistance or prompting from Miss Loi or your classmates (don’t think they will)!

To prevent a potentially fatal incident where a Math Genius gets choked to death by hundreds of marshmallows, these premium questions shall be of sufficient complexity/difficulty such that (barring freak cases) on average only 30% of Miss Loi’s students will get them right on the first attempt.

Now would you please excuse Miss Loi as she pops another marshmallow into her mouth. *enjoys the lofty feeling of great authority!*

### Revision Exercise

Hey..how many questions of that difficulty are there? Lets say there are n questions of that difficulty, an in a month there are 4 sessions, so there are 4n questions.

Let the cost of the rocher be \$r.

Let the cost of enrolling as a student be \$c.

Hello Kenneth!

Now don't be so quick to wager on this! Think you've missed out a very important variable:

Let p be the probability of you answering a question correctly on your 1st attempt.

\$pn4nr > \$c.

Of course if you insist that your p = 1.0, you would have to be reclassified as a Math Genius, and we would then have to work out the probability of you getting choked to death by hundreds of marshmallows!

Students, this is turning out to be a nice probability problem! 🙂

P.S. Don't think you're of the right Temple-going age either! 😉

yeah..I'm not of the right temple going age..haha..the probability of me getting the questions correct should and would be higher than those that are going to your temple..for one, i'm much older to go to the temple, and the 2nd is i've been consistent so i need not go to temples..lol..
