Hey people
I have got a mathematical problem to solve. I have report about that problem with a question, hypothesis and all the mathematical explanations and calculations. So the problem is:

"You are a wealthy parent of 10 children. You have a safe with a lot of money. Your children should get the safe open when they are with 3."

I have generated a question so my question is:
How the code of the safe would be made so that mimimum 3 children can get the safe open?

Pls reply me asap as I have not so many day left for this. I only want an idea how can I solve this.. :(

What is meant by the children "being with three"? (Is this being translated from some non-English language?) Thank you! ;)

haha.. yes but I didn't translate that. I just wrote that according to my English lol:D. But I meant if the 3 children go together then only they can get that safe open.
Here is something I thought today but it's also not correct.
So I have to make a code. It can contain some common numbers but the numbers should not be repeated more than twice. For example you have chosen 010101 as a code. You divided it per two numbers eg.01 under all of your 10 children. So if 3 children go together, every one of those 3 type their code in. eg. Child 1 type his code 01, child 2 also 01 and child three also 01 then we have got our right code.
But the problem is we can’t use one number more than two times. We can use a number for two times only but here I have chosen three times so it’s not a suitable code.
 
Well, quite unclear still: do you know someone familiar with English?

Looks to me like each child has a separate secret password,
and the safe can only be opened if any 3 of these passwords
are entered.

Yes exactly, you got it right. Now pls can anyone solve this for me. I have to report about it on the upcoming Friday
