    mr. 80 why don’t you try to figure it out so you can prove ICOT wrong?

    #1069183

    its too simple and obvious

    i dont want to embarrass anyone

    The value of e can be derived in a number of ways.

    By definition, substituting a large number for x into (1 + 1/x)^x will give you an approximation.

    Using a Taylor Series will give you =>

    e = 1/0! + 1/1! + 1/2! + 1/3! ….

    Obviously the more terms in the infinite series you use, the better the approximation.

    (x! = x * (x – 1) * (x – 2) … * 3 * 2 * 1)

    No, sorry, I was talking to Squeak.

    We seem to be having a disconnect somewhere and I was hoping to get it resolved before I leave for the day.

    icot does not make mistakes

    1) Wow – how can I meet that guy? I never met anyone like that before.

    2) There’s a poster with a SN like that, but you’re clearly not referring to him, since on the following post he starts with all of the characters on the west bank of the river, then provides a solution which begins with all characters on the east side of the river

    3) Did I ever tell you about the time I tested a copper tubing gas line splice with a cigarette lighter? (true story)

    How about this?

    Offer the canibals some of the fine aged hard cheese that you always carry with you. Once they have eaten, point out that they must now wait six hours until they eat meat. You now have a six-hour window in which to cross safely.

    Ok, Ok…

    we have three canibals and three tourists on the east side of the river, needing to cross to the west bank in a two-person canoe.

    There can never be tourists on the same side of the river as a larger number of canibals.

    Key:

    C = canibal

    T = tourist

    W = west side of river

    E = east side of river

    1) 2 canibals cross together

    result – e=3t,1c w=0t,2c

    2) 1 canibal comes back alone.

    result – e=3t,2c w=0t,1c

    3) two canibals cross together

    result – e=3t,0c w=0t,3c

    4) 1 canibal comes back alone.

    result – e=3t,1c w=0t,2c

    5) two tourists cross together

    result – e=1t,1c w=2t,2c

    6) 1 tourist and 1 canibal come back together.

    result – e=2t,2c w=1t,1c

    7) two tourists cross together

    result – e=0t,2c w=3t,1c

    8) 1 canibal comes back alone.

    result – e=0t,3c w=3t,0c

    9) two canibals cross together

    result – e=0t,1c w=3t,2c

    10) 1 canibal comes back alone.

    result – e=0t,2c w=3t,1c

    11) two canibals cross together

    result – e=0t,0c w=3t,3c

    #1069192

    icot your original answer was correct!

    however to work it out, you have to consider quantum probability waves and the possibility of a worm hole connecting two sides of a localized warped spacetime region

    That equation is the real McCoy – it was too taxing for my intrepid PC.

    I didn’t think it would faze ‘er, but it caused a problem with the cd-romulan drive.

    It’s Elementary

    (for all the math mavinim – and others, too)

    Go from ONE to TWO in nine easy steps.

    Start with O-N-E, finish with T-W-O and insert eight three-letter words between them.

    Each three letter word must be valid (in the Scrabble dictionary).

    Each three-letter word can only have one letter different from the preceding word.

    Truth To Tell

    As you journey through the black-and-white world of logic puzzles, you arrive at the inn in the town of YinYang.

    The denizens of this town either tell only the truth or only lies.

    Fortunately, each citizen wears a cap with an embroidered “L” if he’s a liar or a “T” if he’s a truth-teller.

    Unfortunately, today is laundry day, and all the caps are in the wash.

    You approach a table at which four men are seated and ask “Which of you is a truth-teller?”

    Here are their answers:

    Rube – “More than one”

    Sy – “At least two”

    Leo – “Fewer than four”

    Jim – “Exactly three”

    Who (if anyone) is telling the truth?

    Who (if anyone) is lying?

    How do you know?

    (from a puzzle magazine)

    Truth To Tell – Answer

    #1069198

    Who was the last man to be pictured on the front of circulating U.S. coins who was never a president of the U.S.?

    Which coin?

    Was it Ben Franklin on the Franflin Half Dollar?

    #1069200

    ICOT- the answer to the riddle (in plain english)is:

    key- C= Cannibal

    W= Whiteman

    1C and 1W cross and 1C comes back

    2C crosses and 1W comes back

    2W crosses and 1C and 1W comes back

    2W crosses and 1C comes back

    2C crosses and 1C comes back

    2C crosses

    (the riddle was from before yom tov so here it is again, You have 3 canniballs and 3 whitemen that have to cross a river. They have one boat that can hold 2 ppl.

    How is it that they can all get across (don’t forget that s/o has to bring the boat back) but at any time on either side there can’t be more cannibals than whitemen?)

    #1069201

    Dr. Pepper

    Correct!

    Ben Franklin was on the half-dollar from 1948 thru 1963

    In 1964 John F. Kennedy replaced Franklin.

    Other circulating coins last had non-presidential men on their obverses as follows:

    Nickel – Indian, 1938. Replaced by Jefferson in 1938 (there was an overlap).

    blinky

    Your first step – 1C and 1W cross and 1C comes back – leaves three cannibals and two suppers on the original riverbank.

    I can only try

    There were some 1964 Peace Dollars minted for circulation in 1965 although they were never actually released for circulation.

    Hey ICOT you are right (i guess mod 80 had a point when he said u are never wrong)

    1) C & MI cross

    2) MI returns

    3) C & C cross (now all cannibals are across, and all MI at square 1)

    4) C returns

    5) MI & MI cross

    6) C & MI return

    7) MI & MI cross (now all MI are across, and all but 1 C at square 1)

    8) The 1 cannibal who is across will make 2 ferry trips to bring his or her companions across one at a time.

    My closing comment in my first solution attempt at least was correct.

    Mosh3-

    Here’s one for you-

    Let’s say you have a table with equal distant parallel lines running the length of the table.

    You randomly drop a pencil onto the table.

    What are the chances of the pencil hitting a line?

    Extra Credit- If the length of the pencil is shorter than the distance between two consecutive lines- what famous constant will you estimate?

    (No asking Squeak or I can only try.)

    Lemme guess Dr. P. You were counting the posts and timed yours to hit the jackpot…

    #1069213

    Dr. Pepper

    True.

    I discovered that fact about 10 minutes before you posted it, while confirming the dates on the PCGS site (a casual coin-collector like me needs confirmation).

    blinky

    That must be why I mentioned Lady Liberty as being the last non-presidential man on the dime, quarter and dollar coins.

    1) You can start with a cannibal and tourist crossing together and the tourist coming back, OR, two cannibals crossing together and one coming back.

    2) The last trip back to pick up the remaining cannibal can be made by either a tourist or a cannibal.

    in the future please email me your “riddles” so i may correct the verbiage before you give us prodigies a headache trying to unravel your intent.

    ps if you didnt understand my previous post ill put it in “normal” human terms. your riddle was somewhat ambiguous (that means that it lends itself to more than one understanding)
