Probability curves showing poisson's exponential summation

摘要: IN many importa nt practical operations the constant probability of an event happening in a single trial is extremely small. but number trials so large that may actually occur sufficient times to become matter importance. The curves Figs. 1 and 2 show P such at least c for which average occurrences a. range shown from 0.000001 O.999999 extends 0 15 Fig. 200 2. An open scale obtained both ends, even when approaches within one part million limits 1, by employing ordinate corresponding normal integral.
