Formulas for crit and deathblow probability

Pasha J.S.:
Using this formula, the probability of inflicting normal hits, critical, lethal and crit-lethal hits was calculated.

Critical hit chance: 73%
Fatal Strike Chance: 3.5%

If a fatal hit coincides with a critical hit, the result is critical-lethal damage.

Normal Strike: 100
Critical Strike: 460
Deathblow: 1360
Critical-lethal strike: 6256

Calculation of probabilities (assuming independence of events):
Regular hit = (1 − 0.73) × (1 − 0.035) = 0.26055 (26.055%)
Critical (non-lethal) = 0.73 × (1 − 0.035) = 0.70445 (70.445%)
Fatal (no critical) = (1 − 0.73) × 0.035 = 0.00945 (0.945%)
Critical + Lethal = 0.73 x 0.035 = 0.02555 (2.555%)
