Little Mathmatics
kureshii:
Wait, when did the lounge turn into #elementarymathematics?
Also, idgi. Is matchmatics supposed to be a pun or something?
Unfair:
(1/10)*(1/9)*(1/8)*(1/7)*(1/6)*(1/5)*(1/4)*(1/3)*(1/2)*(1/1)=1/(10!)=1/3 628 800≈2.755731922*10^-7≈0.000000276
and, for percentage. Take times 100.
soo...
answer:
1:3 628 800
or
≈0.0000276%

Thanks.

You have a chance of 1/10 to pull the first marble, then a 1/9 chance to pull the second, a 1/8 to pull the third, ....
In the end you have to multiply all factors and get 1/10*9*8*...*2*1 = 1/10! = 1/3628800 or 0.000000276%

Nice, thanks.
There is no homework involved in this. I was just wondering about this in my head. We have supposedly about 200 billion stars in one universe if I'm correct? Or is it more?

Not by a long shot, but that is likely a pretty conservative estimate for the number of stars in our own one galaxy, the Milky Way, to which we have more galaxies in the universe then our galaxy has stars.
Also- Why was I suddenly reminded of the Drake Equation when you asked that =p
Perhaps because you were asking the odds for the perfect conditions.
