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
