LOCKS
[size=7]Given:
T = total number of people
R = required number of people to open safe
L = number of locks
K = number of keys per person

I believe the general formula is:
L = C(T,R-1)
K = C(T-1,R-1)

C(13,7-1) = 13!/(6! * 7!) = 1716
[/size]

TTH:
n! means n factorial, which is n * (n-1) * (n-2) * ... * 2 * 1
2! = 2
3! = 6
4! = 24
5! = 120

0! is defined to be 1.

The number of ways you can choose 7 out of 13 A2K'ers is 13!/(7!*6!) = 1716, where x! = 1*2*...*x.

Next put 1716 locks on the safe, one for each way to group 7 A2K'ers.
For each lock give 7 keys to a unique group of 7 A2K'ers. This way any given lock will have a keyholder in any group of 7 or more.

For any group of 6 there will be exactly one lock in which the other 7 A2k'ers have the key. Obviously any group of less than 6 would also be missing at least one key to at least one lock.

Here are the number of keys required for other numbers of A2K'ers:

Code:

A2K'ers… Number of Locks

A2K TABLE
Two possibilities: 5" or 25" Cool Cool


What! Two answers - set the radius of the table be r.
Denote the corner of the room (0,0), the point of contacts (0,r) and (r,0) and the point on the edge in question (10,5).
Draw a triangle with these points (10,5), (r,5), and (r,r). This is a right triangle with sides of length r-10, r-5, and r. The pythagorean formula tells us that (r-10)^2 + (r-5)^2 = r^2. Solving for r yields r =5 and 25 inches.

Dang! He is right again… Very Happy

Hi Try,, i met a girl who seemed as if she could have been Epiticus' daughter (at a homeless shelter in Portsmouth, N.H.)

I met a Dark Age man named Dean ~. Yeggies ~

What's going on here? Nothing; that's what's going on!.....
I've seen more action from a bag of nails!

Still, I suppose if you have taken the trouble to visit; I should tell you a story about how Mismi and the Professor first met:

There was this Professor, on a cruise ship in the Caribbean for the first time. It was wonderful, the experience of his life. He was being waited on hand and foot. But, it did not last. A Hurricane came up unexpectedly. The ship went down almost instantly.

The Professor found himself, he knew not how, swept up on the shore of
an island. There was nothing else anywhere to be seen. No person,
no supplies, nothing. The man looked around. There were some
bananas and coconuts, but that was it. He was desperate, and
forlorn, but decided to make the best of it. So for the next four
months he ate bananas, drank coconut juice and mostly looked to
the sea mightily for a ship to come to his rescue.

One day, as he was lying on the beach stroking his beard and
looking for a ship, he spotted movement out of the corner of his
eye. Could it be true, was it a ship? No, from around the corner
of the island came this row-boat. In it was the most gorgeous
woman he had ever seen.

Mismi was tall, tanned, and her dark hair flowing in the sea breeze
gave her an almost ethereal quality. She spotted him also as he was
waving and yelling and screaming to get her attention.

She rowed her boat towards him. In disbelief, he asked, "Where did
you come from? How did you get here"?

Mismi said, "I rowed from the other side of the island. I landed on
this island when my cruise ship sank"

"Amazing", he said, "I didn't know anyone else had survived. How
many of you are there? Where did you get the row-boat? You must
have been really lucky to have a row-boat wash-up with you?"

"It is only me", she said, "and the row-boat didn't wash up,
nothing else did."

"Well then", said the Professor, "how did you get the row-boat?"

"I made the row-boat out of raw material that I found on the island",
replied the woman. "The oars were whittled from Gum tree branches,
I wove the bottom from Palm branches, and the sides and stern came
from a Eucalyptus tree"

"But, but", asked the Professor, "what about tools and hardware, how did
you do that?"

"Oh, no problem", replied Mismi, "on the south side of the
island there is a very unusual strata of alluvial rock exposed. I
found that If I fired it to a certain temperature in my kiln, it
melted into forgeable ductile iron. I used that for tools, and
used the tools to make the hardware. But, enough of that", she
continued. "Where do you live?"

At last the professor was forced to confess that he had been sleeping on
the beach.

"Well, let's row over to my place", she said. So they both got
into the row-boat and left for her side of island. Mismi easily rowed them around to a wharf that led to the approach to her place. She tied up the row-boat with a beautifully woven hemp rope. They walked up a stone walk and around a Palm tree, there stood an exquisite house painted in blue and white.

"It's not much", she said, "but I call it home. Sit down please,
would you like to have a drink?"

"No", said the Professor, "one more coconut juice and I will puke."

"It won't be coconut juice", Mismi replied, "I have a still,
how about a Pina Colada?" Trying to hide his continued amazement,
the man accepted, and they sat down on her couch to talk. After a
while, when they had exchanged their stories, Mismi asked,
"Tell me, have you always had a beard?"

"No", the man replied, "I was clean shaven all of my life, and
even on the cruise ship"

"Well if you would like to shave, there is a man's razor upstairs
in the cabinet in the bathroom." So, the Professor, no longer
questioning anything, went upstairs to the bathroom. There in the
cabinet was a razor made from a bone handle, two shells honed to a
hollow ground edge were fastened on to its end inside of a swivel
mechanism. The man shaved, showered and went back down stairs.

"You look great", said Mismi, "I think I will go up and slip
into something more comfortable." So she did. And, the man
continued to sip his Pina Colada. After a short time, Mismi
returned - this time wearing fig leafs strategically positioned
and smelling faintly of gardenia.

"Tell me", she asked, "we have both been out here for a very long
time with no companionship. You know what I mean. Have you been
lonely, is there anything that you really miss? Something that all
men and women need? Something that it would be really nice to have
right now?"

"Yes there is", the Professor replied, as he moved closer to Mismi
while fixing a winsome gaze upon her, "Tell me .........................


















Do you happen to have an Internet connection?" Shocked

The rest as they say is history! :wink:
