**shortee**, Saturday, February 28, 2009 at 7:21pmOkay so there are 16 colors in all.

so the variable that it's black is 0/16 because there are no black.

the variable its yellow is 3/16.

the variable it isnt red is 13/16

**PsyDAG**, Sunday, March 1, 2009 at 11:21am**Shortee**missed the fact that there are 6 black marbles in the bag, so the probability of black is 6/16 or 3/8. However, the rest of his information is correct.

All he is doing is taking the number of drawings that fit the description and dividing by the total number of possibilities.

I hope this helps a little more. Thanks for asking.
