Hi everyone,
The week is starting to liven up. There were some great answered supplied by Alan, I like Serena, Bluefrog and kitty<3. Thanks you.
Brainiebean123 joined today. Welcome to Web2.0calc forum. We hope you like it here. Looking at the posts that you made today I think you and reinout-g might get along well. He likes providing puzzles, Maybe he can find some that you like.

Information for new people.
There is a private message system here. If you left click on your username you will find it. If you go into the user control panel then Board Preferences, you can get a pop-up display for new messages, that is if you wish to do so.
If you send a message it will sit in your outbox until the recipient opens it. In the mean time you can edit it or delete it if you wish. It only moves to sent mail after the recipiant opens it. It is a really cool system. i wish my usual email worked this way.

I sent another email to Andre Massow today regarding Latex. My letter was very similar to the one i presented to you two days ago. I also reiterated my need for moderator privileges. The detritus around here really needs to be cleaned up. I would not abuse any privilege that I was given. I would be encouraging core members to help mould conduct policies. Anyway it is all irrelevant at the present time .

I think that just about sums things up on this Monday evening. I just realized, it has been Sunday in many places. My the place is getting busier.
Anyway, enjoy the new week.
Melody.

Hard one :
Three kids named Brooks, Clint and Riley have a new game using water balloons.
They each take turns trying to throw one balloon at one of the other two. If they hit, the person is out, otherwise the next person may take his turn.

Brooks hits 1/3 of the time, Clint hits 2/3 of the time and Riley never misses.
Brooks is allowed to start, then Clint (given that he is still in the game), then Riley (given that he is still in the game), etc.
Where should brooks aim during his first turn?

Well if Brooks misses both targets then Clint will definitely try to hit Riley. Because if Clint hits Brooks, Riley will get him next anyway.
Therefore there is no point in Brooks going for Clint.
Now if Brook hits Riley then Brook has a 2/3 chance of being hit next
If Brook misses altogether then he has no chance of being hit next, If Clint hits Riley then it is Brooks turn next anyway (he'll get another shot at clint). If Brook misses Riley then there is probably a less than 2/3 chance that Riley will target Brook next.

So it seems to me that Brook's best strategy is to purposefully miss both targets.

IS that right ??

Easier one: (still to be solved)
There are 31,542 people attending a concert. One person is picked from the audience and if his birthday is a monday he will win $1.000.000
What are the odds that that persons birthday is a monday?

Er let me see... There are seven days in the week. Everyone has to be born on one of them.
So the chance of anywone being born on a monday is 1/7
