Answer:
16/81
Step-by-step explanation:
There are 9 total marbles, meaning the probability of getting a red the first time is 59.
The second time, there are only 4 red marbles and 8 total marbles, so the chance of getting a red on the second time is 12.
The probability of getting 2 reds is 59⋅12=518.
Hope this helped!
