How This Is Calculated

The probability of getting at least one knife in 1000 cases uses the complement formula: P = 1 - (1 - 0.0026)^1000 = 1 - 0.074023 = 0.9260 = 92.60%.

This formula works because it calculates the probability of NOT getting a knife 1000 times in a row (which is (1 - 0.0026)^1000), and then subtracts that from 1 to get the probability of getting at least one knife.

With 1000 cases, you have better than even odds of receiving at least one knife. However, a 7.40% chance of no knife is still substantial and should be expected as a realistic outcome.
