We calculate probabilities based not on sums of discrete values but on integrals of the PDF over a given interval. In general, the probability that a continuous random variable will be between limits a and b is given by the integral, or the area under a curve.

1.3 Deterministic and Statistical Models A deterministic model is one that makes no attempt to explain variability. For example, in circuit analysis, Ohm’s law states that
