you chose the rain drops are You did well, many people say this is random. In fact, a common problem is that we believe random things are more uniform than they are. This is true on average for large numbers of things, but when we are dealing with relatively small numbers things are typically far more uneven. In this pattern there are exactly 5 rain drops on every tile. It is just possible that this happened by chance - but extremely unlikely. In fact, it was deliberately generated to have exactly the same number of rain drops in each square, although otherwise is completely random. This is an example where there is no non-uniformity or bias in the average distribution, but a correlation between the outcomes of different trials. effectively each raindrop avoided 'overcrowded' tiles! You did well to notice that this was a day of good omens and since many will have missed this, you will be one of the few to take advantage of it!
