So the questions has one in common, Find the probabilities of the following given marbles. So base on my calculation, I came up with the following answers:

#1. Red = 1/9

#2. Black = 16/225

#3. Red once = 5/12

#4. White once = 3/10

I hope you are satisfied with my answers and feel free to ask for more if you have more questions and clarifications. Have a nice day
