Hi Could someone help me?
A clown is two steps from the end of a trampoline and will have to remove 10 balls being 5 red and 5 yellow. When you take out a red ball you take a step forward, and when you pull out a yellow ball you step back. How many ways can you draw the balls so that the clown does not fall?
Answer : 132
Thanks
