You have to say, what is the probability of me getting between, let's say, a 4.5 and a 5.5? You have to give it some range. And then your probability isn't given by just reading this graph. The probability is given by the area under that curve. It would be given by this area. And for those of you all who know calculus, if P of x is our probability density function, it doesn't have to be a normal distribution, although it almost always, well, it often is a normal distribution. The way you actually figure out the probability of, let's say, between 4.5 and 5.5, what is the probability, this is whatever, the odds of me getting between 4.5 and 5.5 inches of rain tomorrow.
