Including 1, which isn't consecutive I see 6---well 5 not including 1
0th is 1 and is 2007 Cool Cool Cool

1st consecutive is 2 and starts with 1003
2nd is 3 and starts with 668
3rd is 6 and starts with 332
4th is 9 and starts with 219
5 th is 18 and starts with 103


Great answer!



There are five ways to write 2007 as the sum of consecutive positive integers (six if you count the trivial one-term sum).

Adding the k integers starting with s yields k(2s+k-1)/2. For this to equal 2007, k must be a divisor of 4014.

For six of the possible values of k (including 1), the corresponding value of s is positive.

Jo, "As many as the smartest …..Not much of an answer is it?"

It is a good answer; the afternoon question can usually be answered by so few, we are very lucky that a few of the few pass this way and give us the benefit of their talent. And to those brave guys I say…

The gratitude of every home in the land, and indeed throughout the world, except in the abodes of the guilty, goes out to you who, undaunted by odds, unwearied in their constant challenge and mortal danger, are turning the tide of ignorance by their prowess and by their devotion.

Never in the field of human conflict was so much owed by so many to so few. All hearts go out to the unsung heroes, whose brilliant actions we see with our own eyes day after day… Amen

• It was supposed to be: MIND OUT. But you made more sense of it than I did! Embarrassed



A gambler has in his pocket a fair coin and a two-headed coin. He pulls one of the coins at random from his pocket and, when he flips it, it shows heads.

(a) What is the probability that it's the fair coin Question

Suppose he flips the same coin a second time and again it shows heads.
(b) Now what is the probability that it's the fair coin Question

Suppose that he flips the same coin a third time and it shows tails.
(c) And now what is the probability that it's the fair coin Question



And now for something completely different.

Theorem - Horses have an infinite number of legs!

Proof - A horse has an even number of legs.
It has Forelegs on the front.
It has two legs behind.
Six legs is an odd number of legs for a horse to have.
The only number that is both odd and even is infinity.
Therefore, horses have an infinite number of legs!

[size=7]Start with two coins, a fair coin and a biased coin. the probability of picking either coin is 50:50.

Start with fair coin,
1 head =prob of fair coin (1/2)* prob of head(1/2)=1/4
2 heads=fair coin(1/2)*prob of two heads(1/2*1/2)=1/8
3 heads=fair coin(1/2)*prob of three heads(1/2*1/2*1/2)=1/16

biased coin
1 head=prob of biased coin (1/2)*prob of head(1/1)=1/2
2 heads= the same (1/2)
3 heads=the same (1/2)

Prob of 1 head=3/4
Prob of 2 heads = 5/8
Prob of 3 heads =9/16

1 head prob of fair coin =(1/4)/(3/4)=1/3
2 head prob of fair coin = (1/8)/(5/8)=1/5
3 head prob of fair coin = (1/16)/(9/16)=1/9

Oh! I get it, he tosses a tails the third time---it's the fair coin fer shure!

I can speak for all, when I say that was a particularly well explained answer! Very Happy



The answer was: 1/3, 1/5, 1

a) There are two events: The selection of a coin -- resulting in the Unfair Coin, "U", or the Fair Coin, "F" -- and the flip -- resulting in heads, "H", or tails, "T", for the Fair Coin, and in one of the two heads, "H1" or "H2", for the Unfair Coin. Each of these events is considered a 50/50 proposition.

Event1 Event2
F H
F T
U H1
U H2

So the conditional probability P(F|H) = P(F and H)/P(H) = (1/4)/(3/4) = 1/3.


b) Similarly,

Event1 Event2 Event3
F H H
F H T
F T H
F T T
U H1 H1
U H1 H2
U H2 H1
U H2 H2

Now P(F|H,H) = P(F and H,H)/P(H,H) = (1/8)/(5/8) = 1/5.

c) It must be the fair coin. P(F|H,H,T) = 1.

Hi Try,,, the minute i was let out of jail,,, after i was wrongfully jailed,,, i had an uncontrollable urge to smoke a cigarette. It was like after the pope died,,, i quit for 3 day's and then i took a drive and smoked cigarettes again.

I prayed feverishly to quit,,, but,,, i guess it just isn't in the stars for me to not smoke cigarettes, seeing how i have NO money what so ever.

It sure is difficult to get a job to support a habit that i prayed not to have.

Want to hear a strange story,,, i called an art dealer in Boston, Massachusettes to see if they would purchase some of my Art Work, they were not interested,,, and hung up. (this might sound crazy but) i can draw and paint pretty good,,, in fact when someone looks at my art work, often times, the first thing they say is

("oh my fk'n God!,,, if they can say anything at all)

If you were a female, like me, what would you do, and where would you go to sell and make money,,, you know a living,,, from a skill that you almost asked for?

Hi Jo, waddaya doing?


Step 1. Choose your artist name. - Not wayway, yoyo, etc.

Step 2. Get pictures of yourself and any work you have done.
(In the first instance black and white will be fine)

Step 3. Issue this Press Release:

Local resident (insert name) who is making quite a name for herself and is highly sought after on the International Art Market was injured when she tried to break up a fight between rival art dealers fighting over the latest work.

The winner of the latest battle was Mr T.R.Yagain of Milan Italy who paid over $2,000. His US spokesperson said, "The work of (name) is much sought after as it reflects an earlier more gental time, a return to childhood innocence if you will."

Even though still recovering from the mishap (name) is still planning to start her next commission. Further details may be obtained from (Contact number).

Good luck.
