Post when you are done and good luck.

]]>It says the forumla to solving the probability of a machine like this is binomial distribution. I will try making an expression witht aht and then I will let you know how it goes.

]]>I have fixed your post to show the images. You do notice that this is close to a standard normal curve.

]]>And this is what I have so far:

And for task one (the task before this one), I had to do an experiment using a pinball machine with 5 cups. (40 balls too):

]]>

I would love to help but to help I need to see a bit of what you have already done and a bit of what you already know.

Some questions, how many balls are put into the cups? Are the cups equiprobable?

]]>The problem I am stuck on tells me to consider a small machine with only two cups. And for that small machine I have to find out the probability of a ball landing in each cup. Then, I have to repeat this process for other machines with 3, 4, and 5 cups. From there I have to use any pattern I see and derive an expression for the probability of landing in the i^th cup from the left in a machine with n cups.

We also have to right the probabilities as fractions (not simplified) so we can find patterns.

Does anyone mind helping me with this?
