I want see the odds of atleast 1 of them being upgraded to +5 I am upgrading Dragon belt from +0 to +5. My chance of getting 1 or more success upgrade ( Cumulative probability: Then my chance of getting exactly 1 success upgrade ( Binomial probability: I have 2 of the items i am going to upgrade. Here i am upgrading something that has 50% chance of succeeding. This is the probablity that you have exactly 1 successful upgrade. This means the probablity of having more or equal number of success than the x value, which is 1.īasically, this shows how likely you are to get 1 or more than 1 successes based on the enchanting rate and the amount of items you are going to enchant.
