I have a specific task in programming but I am curious about how long it will take to complete.
I have an array "A" with 1000 unique numbers inside.
For each iteration I am copying 30 randomly picked numbers from array "A" to array "B".
Duplicate numbers(which already exists in array "B") are not copied
Question is: how many iterations do I need to claim with a certain probability, that all numbers are copied from "A" to "B"
