There Are Ninjas In Singapore

(19)
Posted at 8:09 pm by Miss Loi in A-Level Probability & Statistics Questions
11:59PM AM (TYPO!!!):

Miss Loi waits patiently in the car, with sunglasses on.

12:00PM:

Target appears – spotted walking towards another car. Miss Loi’s eyes brightens. *Grips steering wheel*

12:02PM:

Aunty (i.e. The Target) takes an age to squeeze her groceries into car. Miss Loi getting impatient.

12:03PM:

Aunty completes squeezing of groceries into car. Aunty drives out of parking lot. Miss Loi takes off sunglasses and quickly zooms into vacated lot before the Ah Beng car behind beats her to it.

12:04PM:

After a thorough scan across the horizon, Miss Loi tears her parking coupon (like all good parking citizen should do), as shown below:

Miss Loi's Parking Coupon
Miss Loi’s Parking Coupon
- “scheduled” to start at 12:20PM
12:05:00PM:

Miss Loi hippity-hippity hops away from her car.

1:20PM:

Miss Loi hippity-hippity hops back to find this on her car:

Ninja Shuriken

1:30PM:

A distraught Miss Loi calls Mr Loi:

Bro! You wouldn’t believe how SUAY I was at the carpark just now! I tore my coupon to start at 12:20PM, left my car at 12:05PM, and I got summoned at 12:08PM! They employ ninjas as parking attendants these days is it?!!!!

Mr Loi replied in a calm voice:

Sigh … that is a ‘hot’ carpark with a parking attendant coming every hour. Please brush up your rusty A-Level Probability & Statistics and solve the following question to know your chances of getting caught, and try to lower your probability of getting caught the next time:

Assuming that the parking attendant visits the carpark once every hour, and that the probability of her turning up to check at any given minute is 1/60.

Miss Loi tears her coupon to commence at 12:20PM and left her car at 12:05:00PM.

  1. Find the probability of the parking attendant first appearing at 12:08PM.
  2. Find the probability of Miss Loi getting caught i.e. the parking attendant appearing at anytime between 12:05-12:19PM.
  3. What is the latest commencing time she should tear in her coupon in order to have at most a 10% chance of getting caught by the parking attendant?

* Take each minute as a discrete random variable

1:35PM:

An angry Miss Loi hangs up the phone abruptly :(

The Flesh Is Willing But The Spirit Is Weak

(6)
Posted at 5:08 pm by Miss Loi in Miss Loi's Temple

Able to reach the deepest recesses of one’s consciousness, it’s known that the fresh-scented smoke from Miss Loi’s therapeutic joss sticks has got a calming effect on troubled students’ minds, soothing ruffled nerves on those stressful eves of major exams to let them see the light, when they finally realize at the death that (a + b)2 is NOT a2 + b2.

In these carefree days of the December Holiday Jφss Sticks Sessions, however, a stressful eve of the next major exam is perceived to be still far away.

As a result, this calming effect (coupled with Singapore’s lovely December weather) can sometimes go beyond soothing troubled nerves – gently carrying the unknowing student into an advanced state of thought, where his mathematical spirit departs the body for a (presumably) better place …

Sleeping in Joss Sticks Session
Student in advanced state of thought,
as demonstrated by ability to see through his arms.

… where such defining moments are usually captured by Miss Loi to add to her collection of evidence behind those mysterious abrupt ‘artistic” strokes in students’ workings.

Tsk tsk.

The Temple Walls Are Turning Green!

(8)
Posted at 5:38 pm by Miss Loi in Miss Loi's Temple

The Temple walls are turning green.

The Temple Walls Are Turning Green!
Or “Apple Green”, or “Lime Mist”,
insisted Miss Loi’s kaypoh aunt and Nippon Paint’s catalogue respectively

For a week, ungodly *KNOCK KNOCK KNOCK* *BANG BANG BANG* *KOK KOK KOK* sounds have been heard coming from The Temple.

Tools of the Trade
Tools of the trade
for punishing students who never do their homework

Where hammer-wielding men have been turning up daily to hunt down Miss Loi like a scene from a horror movie.

A Hammer-Wielding Man
Yoohoo … Miss Loi … where are you?

Leaving The Temple in a state of mess each day after they leave.

Temple Mess
I’m here! I’m here! Behind that pole!

On another front, a bunch of skill-few people was roped in to turn the walls green.

A Skill-Few Bum
A “skill-few” bum.

However, skill-few-ness began to take its toll, and Miss Loi (and Mr Loi, and Little Miss Loi, and …) had to be activated to join the exercise of a thousand up … down … up … down strokes to finish the job, resulting her having body aches for the next few days. Tsk tsk.

The Terrifying Pores
Terrifying pores that jumped out from paint trays and devoured everyone
(insider joke :P )

But in the end, it was done. Miss Loi’s Temple has finally been extended and metamorphosed to a new shade of green (or “Apple Green”, or “Lime Mist”, says the kaypoh aunt and the paint catalogue respectively), to seal its spiritual colour union with Jφss Sticks.

The Temple Renovated
I Now Pronounce You Temple & Blog *wedding bells*

Admittedly, things are not 100% running yet. But that’ll do for now to welcome her new batch of students to kick-start Day One of tomorrow’s December Holiday Jφss Sticks Sessions.

がんばって!!!

Where Is Miss Loi?

(7)
Posted at 7:35 pm by Miss Loi in Miss Loi the Tutor

A week has passed since the War ended, and like hungry ghosts *choy* they spewed forth from the Temple Gates, towards that irrepressible taste of freedom.

The fact that Judgement Day comes early next year is swiftly forgotten, as they suddenly found themselves to be Mathematical refugees no more, as their attention turned to more urgent life-and-death matters like how to avoid looking like a drag queen in that upcoming prom.

Two weeks have passed since Miss Loi disappeared from this blog, leaving her brother and sister to mess up fill this blog in her absence with hieroglyphic stuff, some of which she will never understand.

Few knew where she’d gone, though she was last heard to have broken some record concerning the most number of phone calls made in two weeks, after pouring through those on her list, with her ears swollen from listening to the constant stream of tragic 凄凉 tales of academic despair and underachievement.

But there have been sightings of Miss Loi popping up in various locations, like a gathering of hungry ghosts:

The Gathering
Obviously, the photographer’s hands trembled.
Probably spooked by what he saw.

While others have reportedly caught an unglam sight of her sitting by the side of an unknown street, ravenously gobbling down some of the best bak kut teh in the world:

The Best Bak Kut Teh Ever
Nom nom nom …

Before heading towards the hills and subjecting her tiny little frame to be battered by hundreds of centrifugal forces as she zoomed along the long and winding road:

Over The Hills & Far Away
Over the hills and far away

Where she was spotted nursing her swollen ears and camwhoring away in some unknown location:

Secret Destination
Guess where I went?

But regardless of where Miss Loi is, the latest schedules for The Temple‘s December Holiday Jφss Sticks Sessions have somehow magically appeared and are now filling up as we speak.

There’s still time for you to contact Miss Loi to tell her your academic tale and be part of The Temple‘s new batch of salvatees (if there’s such a word). And in return, she might even tell you where the best bak kut teh in the world is.

In any case, it’s great to have finally cleared the list and start blogging again *massages swollen ear*

IMPORTANT: If you’ve pre-booked with Miss Loi earlier in the year but only experienced a long eerie silence till now, please call Miss Loi asap.

Don’t worry, she didn’t abandon you – chances are Miss Loi wasn’t able to reach you when she called. Fate can be cruel at times. *sigh*

がんばって!!!
