Put one white marble in one bowl. The rest of them in other. Probability of picking bowl with one white marble is .5 and that of picking a white marble out of it is 1. Probability of picking up the other bowl is also .5 and that of picking a white marble out of it is 49/99. Total probability = (.5*1)+(.5*49/99)= 0.75
