“-Two pairs, aces high… -Pass. -Ha ha… I told you so: the tide is turning! Three of a kind.
– Hum… chance is not an element whose variations may be analyzed. Randomness is pure… To regulate it would mean that martingales exist…
but they don’t! By the way, talking about chance, do you know that this word comes from the ancient french word “chéance”, meaning “the way dice fall”?”

* Info about the exam:

    – It will take place on Friday, January 22, 2010, from 12:15 PM to 15:15 PM, in room CO 3.
    – You will be allowed four one-sided A4 pages with handwritten formulas only.
    – For the Christmas break, you will receive a quiz (ungraded) to help you revising the class,
    and an “answers session” will be organized on Friday, January 15, at 2:15 PM in room INR 113.
    NEW: The solusions have now been posted at the bottom of this page, but watch out that the exam is not only a quiz!
