Concept explainers
If λ > 0 and α is a positive integer, the relationship between incomplete gamma integrals and sums of Poisson probabilities is given by
a If Y has a gamma distribution with α = 2 and β = 1, find P(Y > 1) by using the preceding equality and Table 3 of Appendix 3.
b Applet Exercise If Y has a gamma distribution with α = 2 and β = 1, find P(Y > 1) by using the applet Gamma Probabilities.
