Question 431630: Drawing Colored Marbles from Boxes. A bag contains fifty blue and fifty green marbles. Two marbles at a time are randomly selected. If both are green, they are placed in box A; if both are blue, in box B; if one is green and the other is blue, in box C. After all marbles are drawn, what is the probability that the numbers of marbles in box A and box B are the same?

the probability is one ___ the numbers must be the same

the blue and green marbles are evenly matched, fifty and fifty

each time a single colored pair is drawn, there is now an "extra" unpaired marble of the other color
___ this extra marble must eventually be drawn along with one of the same color

the number of marbles in the A and B boxes can be anywhere from zero to fifty, but it is the SAME for both boxes
