Sum 4
Sum 4 is a low result that tradition reads as a warning of disappointment.
Interpretation
It is read as a setback in small things: the plan won’t work out as intended, and expectations will turn out to be too high. It is not a catastrophe, just a gap between what you want and what you will get.
A common addition in the collections: the cause will not be chance but a miscalculation — not enough preparation or information.
Probability
Three dice give 216 equally likely outcomes (6 × 6 × 6). A sum of 4 comes from 3 of them, or 1.4%.
For comparison: the most frequent sums, 10 and 11, come up 12.5% of the time, and the rarest, 3 and 18, 0.46% of the time.
The closer a sum is to the middle, the more often it comes up, and the traditional interpretations take this into account: the extreme sums have the sharpest meanings.
Advice
Check your starting facts before you act. One unverified fact in your affair is worth double-checking yourself.
