What am I doing wrong? (Probability)
The question is:
A large bag of marbles contains equal amounts of each of 5 colors (red, orange, yellow, green, and blue). Joaquin selects 1 marble, looks at it, puts it back, and then selects another. Find the probability of Joaquin selecting a yellow marble both times.
___
I figured I had to find the probability of picking a Y out of 10 marbles. (I just chose ten as it would be easiest?) So that means there would be two Y marbles in said bag.
So, total = 10
And each time, you should have 2/10 as the probability of piking out a Y marble.
