If you replace the marble inside the bag, then the total number of marbles remains the same. (2/10) * (5/10) ==> 10/100

Total marbles in the bag = 10 Number of red ones = 3 Probability of pulling a red one on the first draw = 3/10 = 0.3 Total marbles remaining after the first draw = 9 Number of green ones = 5 Probability of pulling a green one after a red one has been withdrawn = 5/9 Probability of both outcomes = (3/10) x (5/9) = (15/90) = 1/6 = (16 and 2/3) percent.
