Probability Calculator
This is a probability calculator for summoning heroes in the noble tavern. It's based on the EXACT amount of heroes you could obtain in 1, 5 & 10 attempts.
Due to rounding, probabilities below 0.05% are defined as 0%.
Formula

P is the probability of obtaining the exact success, n is the amount of tries (like 2700 Crystals is a pull of 10 heroes), k is the amount of successes (like, pulling 2 elite heroes in those 10 pulls) and x is the probability of the individual card (Common is 51.69%, Rare is 43.70% and Elite is 4.61%, as specified in-game).
When Can You Expect 1 Elite Hero?
On average, you can expect 1 Elite hero every 21.69 pulls (22 rounded upwards).

Pulling At Least 1 Hero
