Do the Math

Blame it on the flu. Blame it on the boredom of having spent the last 48hrs trapped at home. Blame it on the conjunction with the final year exams (not as if it really concerns me)...I'm going cranky. Thereby, resulting in this peculiar post.
__________________________________________


If Grace has 5 senses, and 3 (hearing, sight and smell) of them are failing. How many working senses are there left? What is the probability of her surviving the flu epidemic in this urban society?

Un/Fortunately for Grace, her most prized (at the same time, cursed) asset (aka taste) is still functioning. In order to feed herself, she works 12-9pm @ $6/hr twice a week, on top of the 'once-in-a-blue-moon' coaching (where the kids are breaking for exams in the month of September).

ASSUMING...
- Her stomach and appetite is 50% more than the ordinary person and she spends an average (over a week) of $15 on food and expenses each day she goes out of the house... (and she solely leaves home for work, thrice-a-week trainings and only meets up with friends on saturdays)
- Her coaching payment for the month of August is yet again delayed, and her new ad-hoc job's payment has not been processed...

What is the total deficit amount Grace has to ready herself for in the month of September?


Luckily for Grace, she has $y amount of money in her bank account to cushion the expenses before her August/September pay comes in. However she just paid for her driving lessons which cost $220.42, and her very overdued M1 bills which cost $20x.xx.

ASSUMING, $y<$600... and Grace keeps up her eating spree, how long will it take before she turns into a miser again.. (if she isn't already one)?


Driven to desperate measures, Grace decided one day to open up her 'La Bi Xiao Xin' piggy bank and count the number of $1 coins she so infrequently deposits into the hungry boy.

There were 3 $1-coins dated '1988', 5 $1-coins dated '1990', 2 $1-coins dated '1991', 7 $1-coins dated '1995', 13 $1-coins dated '1997', 6 $1-coins dated '2006'.
If Grace puts in all the coins back into XiaoXin, what is the probability that she will shake out a '1997' coin from the pigeon hole? When will Grace get hold of a $1-coin dated '1985'?

Grace took out 3 $1-coins dated '1997' from XiaoXin, how much is his stomach worth now? What is the probability that, in the midst of pulling the plug out of the pigeon hole from Xiaoxin's base, Grace would actually break Xiaoxin's toothbrush even though she was only using 75% of the strength she exerts during weights training? What are the chances that Grace will find the time or be bothered to glue the toothbrush back again?

_____________________________________________

Fact 1: Taking her clumsy ways into account, there is 85% possibility that whenever Grace is around, accidents would happen. - which is part of her concern to whether she should take up driving after all as she does not wish to be a road hazard and she can save up the money at the same time.

Fact 2: Grace has spent 1/3 of her working time blogging the current post at this god-forsaken shop and she has closed 3 sales so far and she is happy.

Fact 3: The date of this post is erred so as to conceal the fact of the current location she is supposed to be at and prevent students from stalking her at her workplace.


P/S: For those who took the time to work out the sums... ... good luck to you. I do hope you manage to answer the rhetorical questions and please enlighten me in that regard where possible.
