Just to let you know it is not a thread for football forum, it is about maths! but don't sweat it, I have moved it here. :h:

So there are five balls.

Question 1: what is the probability to draw one certain ball out of five?

The player has to make three draws.

Question 2: which balls have to draw to score 3 or 5 as sum?
Question 3: how many combinations in what orders are possible to score these points?
Question 4: is it a conditional or unconditional probability? both in combination with and if why?

Consider my questions as clues.
