It has been a long while since I posted a mathematics puzzle, so here goes:
A jar has some red balls and some green balls in it, all the same size and randomly mixed up.
There are at least two balls in the jar, but no more than 100.
If two balls are randomly chosen from the jar, then the probability that they are one red and one green is exactly 1/2.
How many balls of each color are in the jar?
The answer is not unique; give all possible solutions.
Note: That probability, p, will never be 1/2 if there are equally many of each color. For example, with 5 of each color, then p = 25/45 = 5/9.
Answer will be given in one week, on April 21[sup]st[/sup].
