A great deal of worthwhile attention is paid here to the ernoulli distribution, the normal distribution, and the Poisson distribution, and so to the concepts of expectation, standard deviation, population samples, and correlations. The final chapter is devoted to some of the basic questions of science, such as the relation between casuality and chance. No special knowledge is required, eyond high school algebra.
