Actually...LR drop chance from the summon was 0.0001 + 0.0001 = 0.0002, which I assume is per card summoned. So for summoning 10 cards the base probability of getting her is 1-(1-0.0002)^10 which can be approximated by 10*0.0002 = 0.002

using the second ticket will give you a probability of 0.002 + 0.02 = 0.022 of getting a LR and the 3rd will give 0.002 + 0.04 = 0.042

this means the chance of not getting a LR after using 3 tickets equals: (1-0.002) * ((1-0.022) * (1-0.042) = 0.935

this means the chance of getting a LR with the 3 free tickets would be around 6.5%
