I have 2 buckets. Each bucket contains green and blue balls The first bucket contains 3 green balls and 7 blue balls. Second bucket contains 7 green balls and 8 blue balls. I want to take those balls with coin toss. If head, I will take 1 ball from each bucket. But if tail, I will take 2 balls from each bucket. What is the propability if all the balls that have been taken have the same color? (sorry for my grammar)
