The fascination of Maths thread

[BrilloPad]

Chantho is correct. The answer is certainly not what I expected.

Mind you I am really enjoying Sasguru's book on stats - I have not got beyond the coin toss stuff and some of the results are amazing! Shows where I went wrong on gambling (I never gamble now as I always lose).

makes me feel thick with just a degree in maths.

I will try to post up some of the stuff from the book sometime...

From another thread -

1/8W+(D-d) 3/8xTQ MxNA. Where:
W: Weather
D: Debt
d: Money due in January pay
T: Time since Christmas
Q: Time since failed quit attempt
M: General motivational levels
NA: The need to take action

women = moneyXtime
time = money
money = root of all evil
women = (sqr root evil)X(sqr root evil)
women = (sqr root evil)*2
women = evil


SA/CM - that was a joke....

isn't there one involving power?

[BrilloPad]

Dilbert's "Salary Theorem" states that "Engineers and
scientists can never earn as much as business executives
and sales people."

This theorem can now be supported by mathematical proof
based on the following two postulates:

Postulate 1: Knowledge is Power.

Postulate 2: Time is Money.

As every scientist knows: Power = Work / Time.

Since Knowledge = Power, then Knowledge = Work / Time.

Since Time = Money, then Knowledge = Work / Money.

Solving for Money, we get Money = Work / Knowledge.

Thus, as Knowledge approaches zero, Money approaches
infinity, regardless of the amount of work done.

Conclusion: The less you know, the more you make.

Daughter has a present of a cup and six dice. When she makes a first throw she gets a set of numbers, some are repeated and so they go back in the cup and get thrown again. How many throws, on average, will it take to produce all the numbers 1 thru' 6?

Have an apple.

Have an apple.

Is this some sort of maths question? If Denny has an apple then gives it to BP, how many apples does he have?

Easy. Work out the probability of doing it with 6 throws - multiply by 6, then 7 throws - multiply by 7, up to n throws - multiplied by n. Add up these numbers and divide by n. Then work out the limit as n tends to infinity.

The actual calculation is left as an exercise for the reader.

Is that NotallThere speak for FUCTIFINO?

[NotAllThere]

Close. More along the lines that I know how to do it (as indicated), but can't be bothered to do the actual work.
