Day 22 – 愛令我自信如恆山

everything went wrong today…….-_-

jung yiu fever……

i think i already improved a lot in achieving 快而準……

but many things dou hai ho 抵死..

well …today my teammates decided to attack me with brainteasers for the whole day while im at work…very fun huh? @_@

1. what’s the expected number of tosses to get 2 consecutive 2 heads or 2 tails?

2. what’s the PE ratio of cash?

3. what’s the angle between the two hands of an analog clock at 3:15?

4. could an irrational number power to an irrational number be rational ?

JUST THAT I’M FROM MIT, DOESN’T MEAN THAT I AM A QUANTITATIVE NERD!!

STOP MISTAKENING ME AS ONE OF THEM….THANKS.
