Answer: 1/6

Step-by-step explanation: There are 9 marbles in total. There are 3 red marbles out of 9, and the fraction is 3/9, simplified to 1/3. Since the marble is not being replaced, there are now 8 marbles. 4 of the 8 marbles are blue. The fraction is 4/8, simplified to 1/2. Multiply the fractions.

1/3 x 1/2 = 1/6

There’s a 1/6 chance.
