Q 62 ANSWER --- It is base 7 In theory, it should also work with base -9.5, but I have never come across a negative, non-integer number base so I am not sure if it is legal ;) F. |

Good to see Philly, Fred and Bill all on this question. As per Fred's request of "Philly doing the hard work" I'm taking a 'stab' at it - the first line of letters all have straight lines in the letters - the second line has curved parts and straight parts - and the third line only has curved parts to the letters. That's the best I can come up with. |

It's good that's the stab that you took Philly, because it's right! Q65 Winner: Philadelphia Q65 Answer: Top Row is Straight Lines, Middle Row is Curved & Straight Lines, Bottom Row is Curved Lines. Microsoft Windows Standings 1.5 1. Fred W - 17 Points 2. William Rothamel - 16 Points 3. Guido.Man - 8 Points 4. Mr. Kevvy - 7 Points 5. Sarge - 5 1/2 Points 6. Dominique - 5 1/2 Points 7. WinterKnight - 5 Points 8. Philadelphia - 2 1/2 Points 9. John McLeod VII - 1 Point 10. Labbie - 1 Point 11. Scary Capitalist - 1/2 Point 12. TBD... Q66 (1 Point) : At a movie theater, the manager announces that a free ticket will be given to the first person in line whose birthday is the same as someone in line who has already bought a ticket. You have the option of getting in line at any time. Assuming that you don't know anyone else's birthday, and that birthdays are uniformly distributed throughout a 365 day year, what position in line gives you the best chance of being the first duplicate birthday?

I think I remember this one from a year or so ago on another group and I'm pretty sure the number was 20, although I can't give the reason for it, lol. But I'll go with 20 anyway. |

That was quick Philly! And yes the answer is right ;) Congratulations! Question 66 Q66 Answer: 20th Q66 Solver: Philly Microsoft Windows Standings 2.0: 1. Fred W - 17 Points 2.

Q66 (1 Point) : A cloth bag contains a pool ball, which is known to be a solid ball. A second pool ball is chosen at random in such a way that it is equally likely to be a solid or a stripe ball. The ball is added to the bag, the bag is shaken, and a ball is drawn at random. This ball proves to be a solid. What is the probability that the ball remaining in the bag is also a solid? Cya' all soon! Luke. - Luke. |

(1 Point) : At a movie theater, the manager announces that a free ticket will be given to the first person in line whose birthday is the same as someone in line who has already bought a ticket. You have the option of getting in line at any time. Assuming that you don't know anyone else's birthday, and that birthdays are uniformly distributed throughout a 365 day year, what position in line gives you the best chance of being the first duplicate birthday? As the question is asked there can only be 1 answer for a 100% chance of winning. That would be position #367 which would cover all posible dates including Feb. 29. Statistically speaking Philadelphia is correct with 20 but that only gives you about a 50/50 chance of winning. ...and you didn't specify a probable answer. I realize my answer is highly improbable but possible. |
