What do you mean? LIke for example, if you have a bag with the follow:

888887777775 The probability would be 11/12

666778999999 The probability would be 1/4 (3/12)

You take the number in total and that is your denominator(Number on bottom)

You take the total number of sevens and eights and that is you numerator(Number on top)

Than reduce as needed.
