Expected Drops from 100 Cases
| Rarity | Expected Count | Probability |
|---|---|---|
| Mil-Spec | 79.92 | 79.92% each |
| Restricted | 15.98 | 15.98% each |
| Classified | 3.20 | 3.20% each |
| Covert | 0.64 | 0.64% each |
| Knife/Gloves | 0.26 | 0.26% each |
How This Is Calculated
The probability of getting at least one knife in 100 cases uses the complement formula: P = 1 - (1 - 0.0026)^100 = 1 - 0.770791 = 0.2292 = 22.92%.
This formula works because it calculates the probability of NOT getting a knife 100 times in a row (which is (1 - 0.0026)^100), and then subtracts that from 1 to get the probability of getting at least one knife.
With 100 cases, you are more likely to receive no knife than to receive one. You would need approximately 267 cases for a 50% chance.
