    First ask yourself if pulling a marble out of the bag will or will not affect the outcome. if you `multiply` the trials, that means the likelihood of pulling out a black marble a second time is rare and unlikely. If you `add` the trials together, the likelihood of picking the black marble is greater and there's a bigger probability that it might happen.
