A janitor at a motel is covering for the clerk while he is in the restroomand 3 men walk in wanting 1 room. The janitor, not knowing the correct rates, says $10 a person for a total of $30. When the clerk comes back and finds out, he tells the janitor the rate for 1 room is $25 and that the janitor needs to give $5 in change. So, with no way to split $5 among 3 people, the janitor pockets $2 and give $1 to each of the 3 men.

(now the problem)
If each man paid $10 and got $1 in change, than they each paid $9. $9 multiplied 3 times is $27. The janitor pocketed $2 for a total of $29. So where is the last dollar to total the original charge of $30?

Its almost a normal distribution, only its biased. Have been searching web can find out what it's called. I'm sure this must be covered somewhere, just not sure where.

"I have developed the power of mind over matter. If one of you will stand in one corner of this room and toss 100 pennies, I will stand in the opposite corner and, through the sheer power of thought, cause those penny tosses to come up heads. Now mind you, I don't claim that each and every toss will come up heads—I haven't yet perfected this skill to the level of 100 percent. But what I will do is produce an impressive number of heads, to the point where you will at least be willing to take my claim seriously."

No, I'm serious... sometimes I wake up in the middle of the night and I look at the clock and it says "03:14" -- or I get in my car and when I turn it on it says "03:14" exactly... Is this some kind of sign? Are there any numbers which keep showing up in your life over and over so they have "magical" significance?

Ok, I know Pi follows 3.14159..., is irrational and may be defined by the ratio between the perimeter and the diameter of a circle. However, with no serious mathematical implications it could be defined as multiple of it, let's say twice: 6.2831... Therefore I suppose the definition is just arbitrary, am I right?
