The probability of the original god drawing cards

The card drawing probability of single payment without guarantee is 0.6%, and the comprehensive probability of guaranteed payment is 1.6%.

The guarantee mechanism is that there must be five stars in 90 rounds, and the number of times will be reset. Suppose that the probability of Genshin Impact drawing gold in each round before the bottom guarantee (before the 90th round) is 0.6%, and the probability of drawing gold in the bottom guarantee (the 90th round) is 100%.

Then let's calculate the comprehensive probability. Please note that the number of times required to extract a gold coin at a time is independent of each other. So we just need to consider the number of times we draw a gold. The probability of issuing gold for just 1 is 0.6%, and the probability of issuing gold for just k is (99.4%) (k- 1) * (0.6%), that is, the probability of not issuing gold before k- 1 is multiplied by the probability of not issuing gold at k time. The probability of eating a guaranteed amount (drawing 90 rounds) is1-the probability of the first 89 gold withdrawals.
