Thanks, but in my question there are 2 pairs of two bags (4 bags) and only 1 ball is drawn from any given bag, so the choice is always 1:100.

The question is really, as these are unconnected events, is a simple product of the single bag probabilities correct?

    hi,

    If you don't care if the balls from the first pair are equal or not, you just want that pair1/bag1=pair2/bag1 and pair1/bag2=pair2/bag2, your answer is correct. The odds are 0.0001 (0.01%).

    But if you want that pair1/bag1=pair1/bag2 and pair1/bag1=pair2/bag1 and pair1/bag2=pair2/bag2, then you will need to multiply another time, and the correct answer will be 0.000001 (0.0001%).
