Hi!
The information we know:
- how many elements are in the pool
- how many elements will be drawn (one by one)
- the weight of element x (or the probability that it will be the first one to be drawn)
- the sum of all elements weight
What I need:
- the probability that element x will be drawn (not important on which position)
Is it possible to form a universal formula for a situation like this or do I need to know all elements weights to correctly calculate the probability of drawing element x?
Thanks!
