If you toss a coin 10 times and it lands heads up every time, what are the chances it will land heads up if you toss it again?

This was asked in an interview with Coa-Cola.

The interviewer has given me 100 marbles(50 white and 50 black) and two empty boxes.
He then told me that he will leave the room and i need to place all the marbles in two boxes.

And When he come back, he will draw a marble from any of the two box and if the marble is white I will be hired.

Also
* No box can be empty.
* All 100 marbles must be placed in one of the two boxes.

So what should I have done?

Can you find out what is missing?

1 3 5
2 4 ?

Hint: It's not six. Think out of the box.
