I am really struggling to solve this problem, I hope someone can help and show me how its worked out as my two methods give different answers.
What is the probability that I would pick out all $5$ red balls from a bucket that contained $5$ red balls and $45$ black choosing one ball at a time without replacing the balls taken.
The fractoral method gives me a different answer than the other. I think it's because they are picked out one at a time rather than all at once Thanks.
