the annual rainfall in California's north valley averages 23 inches. So the rainfall next year will be 23 inches. Is that true beyona reasonable doubt; probably true; or possibly true,or possibly false
probably false, think out what an average exactly is.
It's both possibly true and possibly false.
As you know from grade averages, many different numbers go into making up an average. The likelihood of the North Valley getting its average rainfall in one year, is slim.
