Hi, I need some help with a basic statistics calculation. I have a bag with 70 'X's and 30 'O's. The X's and O's are free to combine with each other to give 'XX', 'OO' and 'XO' with equal probability for each pair formation. What will be the final distribution, i.e. how many 'XX', 'OO' and 'XO' pairs will there be ? Thanks, Herman
