A problem like this???
whoops here it is

What do you think?
the probability of selecting a yellow is 4/20 because there were four yellow out of 20 draws. However, to get the probability of NOT selecting a yellow, it is all the other draws that total 16 out of 20. so 16/20 which reduces to 4/5 which is .8 probability of selecting a marble that is not yellow. hope this helps.
