I can't seem to get my head around this: A random drawing will be held for which there are 900 tickets sold, for which there will be one winning ticket drawn. If you purchased 25 tickets, what is the probability that you will win.
I am pretty sure this follows a binomial distribution, but I don't know how to adopt the models to solve the problem.
Any help / directin would be appreciated. I am looking more to undertsand the problem domain than to get an answer.
Thank you in advance,
