Hello everyone,

I NEED HELP.

I looking for a solution to create between 100.000 and 250.000 probabilities using squares.

On a surface of 176 squares i would like to know how many possibilities there is to put 90 black squares on it.

My point is to find how many black squares I need to create between 100.000 and 250.000 probabilities.

Thanks for your help

I don't know how to explain it but I found that with 3 black squares I have more than 800.000 probabilities. So basically it's impossible to get between 100.000 and 250.000 but I need a confirmation

You're correct.

I assume that you mean "possibilities" rather than "probabilities", and you're using a dot for the thousands separator.

See combinations(click).

[math]\binom{176}{2}=15,400[/math]
[math]\binom{176}{3}=893,200[/math]
