   Right, you are given the guarantee: "that no day will have probability 1.0, if I know it wasn't any day before". The key is that "if I know it wasn't any day before" CAN'T be a false premise. If the teacher secretly fixes the day at Monday

   ajuc. There's not much room to interpret here. We could program this as a betting game. on every day from monday to friday, the student may place a bet of $1000 at even odds, that the test is on that day. "Sure" means the bet has a 100% ch

   You say: "Why? Even if X is always 1, it is a random variable from {1,2,3,4,5}, with distribution {1.0, 0.0, 0.0, 0.0, 0.0}" But IF , insofar as "x is always monday", x is a 'random variable from monday,tuesday,wednesday,thursda

   Also, I just realized what makes the envelope example particularly clear. If I say "even if you open four envelopes first and find them empty" (I still guarantee you will be surprised on the fifth) I'm in a way implying that that has a non

   ajuc: thank you for your answer. Let's look through this in pseudocode. #teacher picks day DayOfTest = "Monday"; #now go through the week. for today in (Monday, Tuesday, Wednesday, Thursday, Friday): print "It's ", today, "

   I see that this is getting upvoted. * Guys, I made a logical mistake here. I said "this is because if it hasn't happened by the last day it can happen"... But this supposes the students know what day it can happen. They might not. For e

   please see my other comment. Your formulation (1) is wrong, and it matters. If x is, as you say "a random variable from the set {1,2,3,4,5}, with unknown distribution" then it is true that you cannot, given the methodology of going thru da

   right, exactly. This whole problem collapses if you don't 'open the envelopes one at a time' while having my 100% GUARANTEE that you won't be sure there's a heart in the one that does have one, after opening any others you've gone through.

    This "paradox" is no paradox at all, and has a ridiculously easy and obvious resolution. As a teacher: 1) you CAN guarantee for your students that there will be a pop quiz Monday through Friday of next week. 2) You CANNOT ALSO guarantee f

    especially if you've had an ethical bypass and are willing to go Zynga on them later. Engineers are a lot easier to push around than angels (or VC's) are.

    I consider Apple's design aesthetic to be the "mercedes" of phones, laptops, etc. I've never mistaken another car for a mercedes (I'm thinking of the e-class), nor have I ever mistaken another laptop for a macbook, nor have I ever mistaken

    Wait, I think I get it. (Sorry, too late to update). This is indeed ingenious. The key is the step from x to y. The women in x who can say "one of my children was born on Tuesday" are the ones who can say "EITHER my first OR my second ch

    This is ridiculous. Let's do some queries on the world: From all women: (some 3 billion) the ones who have exactly two living children: x matches the ones in which it is true for them to say "One of my children was born on Tuesday.". (this

    ANYONE WHO SAYS THE ANSWER IS OTHER THAN 1/2: Let's simplify the question: If a man says "I have two children, one was born on a Tuesday," what is the probability that they are both born on a Tuesday? Is the answer to this 0 or 1/7 in your

    Python doesn't require a reading list. You're basically writing pseudocode, just make sure to indent it properly.

    There is one surefire sign you're a bad programmer: faced with a problem, your reaction is "pshaw, I see how I can solve this..." Whereas a good programmer has the reaction, "uh-oh. I see how I can solve this..." And knows that this is jus

    Now all we need is a place where you can put brandless but fully implemented tech solutions. e.g. "sms to e-mail technology". That brings us to the final piece of the puzzle: a site where you can invest in a "team" that has no idea and no
