    OK, give it a shot- you just might give him the hint he needs to figure it out.

    #1069333

    Dr. Pepper-

    I don’t really know the calculation involved, but using this post of yours:

    http://www.theyeshivaworld.com/coffeeroom/topic/the-riddle-thread/page/32#post-153407

    …and this explanation of nCr (which I think helped me understand it):

    http://www.xtremevbtalk.com/showthread.php?t=112460

    I’ll try this:

    (8 nCr 3) * ((1/12)^3) * ((11/12)^5)

    =

    56 * 0.0005787037037037037037037037037037 * 0.64722784850823045267489711934156

    =

    0.020974976572025986892242036249453

    or about a 2% possibility

    (fractions derived using the Windows calculator)

    Now, here’s homework for the teacher:

    1) If the answer is correct but clumsily done, please show the correct way of doing it.

    2) If the answer is incorrect, please show where the mistake(s) lie(s).

    If that was in response to my answer, give yourself credit for teaching an old dog a new trick.

    I can only try-

    Yes, it was in response to your answer.

    I noticed that the posts are only being approved every couple of hours or so. When I logged on and saw that some where recently approved I wanted to send a quick post before the mod logged off for the night, therefore I only had time for a one word reply.

    Here’s the formula I used in Excel =BINOMDIST(3,8,(1/12),FALSE)

    and how many standard deviations from the mean would winning 3 times be?

    Is this for ICOT or can I answer?

    Nah, go ahead. I wouldn’t know what to do with the answer anyway.

    #1069340

    Participant

    The mean is 2/3 and the variance is 88/144 => the standard deviation is .781735959970572.

    3 is 7/3 from the mean which is 2.98481002897854 standard deviations.

    With somewhat more delay than usual in moderating, I’m thinking that this is the thread to be in- gives everyone a chance to keep thinking about the riddle without seeing anyone else’s answers for a while.

    1. Which English language word is most frequently spelled wrong?

    2. What has one horn and gives milk?

    3. What starts with “T”, ends with “T”, and is full of “T”?

    4. What word becomes shorter by adding letters to it?

    5. What 3 letter English word has an odd start, and even finish, and an infinitely long middle?

    6. What falls but never breaks? Breaks but never falls?

    7. Forward it is heavy, but backward it is not. What is it?

    And finally….

    Finish the pattern:

    1=3

    2=3

    3=5

    4=4

    5=4

    6=3

    7=5

    8=5

    9=4

    10=3

    11=?

    12=?

    #1069346

    #1 is “wrong”?

    #3- teapot?

    #1069348

    yes wrong is spelled w r o n g

    the word begins with letter t, ends with letter t

    and a teapot is filled with T (tea)

    Squeak:

    Here’s my question for you-

    If the binomial distribution is discrete why do you care what the standard deviation is?

    #1069358

    from the land of Figurativeness onto concrete

    I told you, I wouldn’t know what to do with the answer.

    #1069361
    Dr. Pepper
    Participant

    If you tell me what the “wagon” is I’ll tell you why you need it.

    #1069362

    since the binomial distribution is generally discrete you can trust it. there is no standard deviation, every binomial distribution deviates according to its own nature and environment.

    #1069363
    squeak
    Participant

    Since you insist, I will cave.

    If I have a large number of binomially distributed events, I can use the central limit theorem to assess them with a normal distribution and give meaning to the standard deviation.

    Thought you had me there, didn’t ya? I’m not entirely fuddy-duddy.

    #1069364
    Dr. Pepper
    Participant

    There sure is a standard deviation.

    (Given parameters m and q the standard deviation is (m * q * (1-q) )^.5)

    #1069365
    squeak
    Participant

    I assume that in your job you use the binomial for frequency? What about credit scores- or is that only severity?

    #1069366
    Dr. Pepper
    Participant

    squeak-

    You don’t need it in that case, you can use it if you wish.

    Where do you need to use it?

    #7 is “ton”

    (thank you squeak for posting riddles that the general klal can figure out!- no offense doctor p. and others…)

    #1069368
    Dr. Pepper
    Participant

    squeak-

    We use it for both frequency and severity (as long as the variance is less than the mean and the distribution is discrete).

    I don’t work with credit scores.

    Short becomes shorter when adding the er to it.

    OK, you got them all. Here’s another for the general klal to answer (I request Dr. Pepper to wait a bit).

    Hug-a-Rug Drug Company has just gotten FDA approval for a new medical test to determine if a person is allergic to carpet fibers. One in seventy people in the general population are allergic to carpet fibers. In the clinical trial, 1,000 subjects were tested, of which 500 were known to be allergic and 500 were known to not be allergic. The test results were as follows:

    460 of the allergic people tested positive (true positive)

    10 of the non-allergic people tested positive (false positive)

    490 of the non-allergic people tested negative (true negative)

    40 of the allergic people tested negative (false negative)

    Samuel E. Hutchueson, a.k.a. Sam “Sneezy” is the first person to be tested outside the clinical trial. His test results are positive. How certain are we that ole’ Sneezy is allergic to carpet fiber?

    Speaking of ICOT, he posted on this page, but no one answered. I didn’t want to ‘chap’ anything, but now I guess it’s OK.

    6) Buck novel: Call of the Wild, by London (attention Wolfish)

    7) Iditarod commemorates end of this disease: Diptheria

    8) Balto statue in this park: Central Park!

    11) Churchill & Hershiser nickname: (British) Bulldog – one shares half his nickname, the other, all of it.

    12) Laika: Was a Russkie space dog on Sputnik, wasn’t she? Died, though- ah! the dog was “short-lived”, not the fame.

    13) Nipper listened for this: His Master’s Voice (I chuckled at the memory).

    14) U.S. President’s pet Buddy: Clinton (everyone knows Socks the cat, but not Buddy and Seamus. Why?)

    17) The “Dog Star”: Sirius

    18) A small tent: Pup

    19) A type of three-masted sailing ship: Stumped me.

    20) “Searchlight” dog John Reynolds Gardiner: Stone Fox

    blinky- The correct answer doesn’t, but usually people will see an easy solution which is wrong. Maybe I should have worded it differently, to elicit that response.
