Answer:

5/33

Step-by-step explanation:

5/12 * 4/11 = 20 /132 = 10 / 66 = 5 / 33

The probability of drawing a red marble on the first try is 5/12 because there are 5 red marbles and 12 marbles in total. The second time you only have 4 red marbles left and 11 marbles left in total. Multiply them to find the probability of drawing 2 red marbles in a row.
