I am at the third cave. It shows that I have 67% chance dropping Stone, 25% chance Copper and 17% chance dropping Tin . 67 + 25 + 17 = 109% But sometimes I still received nothing . That's so weird. Maybe a typo, 57% Stone?
This is not a typo, the chances does not sum to a total value, means you can still receive nothing from that.
Based on the data you provided:
- First you have 67% chance for getting Stone.
- If it fails, you have 25% chance for getting Copper.
- If it fails as well, you have 17% chance for getting Tin.
If you didn't receive Tin as well, you get nothing.
I hope you understand
