@wc above, you can't just add up the probabilities like 2.1x30, that's poor math right there; it doesnt make sense. Lets say you have 500 rare summon days that makes your probability of getting a 5 star, 2.1x500 = 1050% which makes no sense at all. The OP is right, the probability of at least 1 5star is 47.1%.
