How to solve this probability question


Would you explain your answer to me.

Thank you.
Well, what's the probability it happens on the first spin? On the second? The third? The nth?

He was asking you to think about the answers to those questions!

If you can work out what happens for specific simple cases then you can work out a formula for what happens in a more general case and hence what you have to do to answer the question you posted.
