Tom can change the probability of choosing a blue marble to 10 1 by adding non-blue marbles based on the formula z = 9 x − y , where x is the number of blue marbles and y is the number of non-blue marbles he starts with. For each blue marble, he needs to add 9 non-blue marbles. For example, if he has 2 blue and 3 non-blue marbles, he needs to add 15 non-blue marbles.
