Simple Probability Breakdown
  1. Check your odds of seeing the unit type you want (based on your level).
  2. Calculate the odds of the specific unit appearing in a slot (considering the pool size).
  3. Combine these odds for all slots in a shop.
  4. Use Markov Chains (a series of matrices) to calculate how these odds change with multiple rerolls.
  5. The final matrix after these calculations gives you the probability of getting the desired number of units after your rerolls.
