Say 2 indentical bags contain different numbers of 
and 
counters.
A bag is chosen AT RANDOM and a single counter removed from it without looking.
bag A : 2 3
Bag B : 3 4
If the counter was what was the probability that the bag was Bag A??

I got it it's 2499! 10000! = [10000/3125]+[10000/625]+[10000/125]+[10000/25]+[10000/5]=a number with 2499 0s
Thank you

Hey!
I searched floor funtion, so basically it just "round it down to the whole number" as in my words
Is that somewhat correct?

Thanks for the help, but why 125, 25, and 5 as denominators?

Here is the question:
what is the difference for the equation of "square of 1 - square of 2 + square of 3 - square of 4........+ square of 99 - square of 100"?
I got -5500, is that correct?
Please give any assitance!
Thank you for helping!!!:D

Also I have win quite a couple times where I played against other people and won by black.

Well I think the computer is smarter than the most of us here. The software programmers programmed the chess software to try their best and win us

I agree with Xyz, once the infinite decimal (0.9999) gets multiplied, it's not infinite any more, so
0.9999 X 10= 9.999 ( 1 "9" less)≠ 9.9999
9.999-0.9999=8.9991
8.9991÷9= 0.9999
P.S. This works for any amount of nines
