看见 GUO‘S的 MANUAL 写到

Difficult distributions such as negative binomial, hypergeometric, Weibull, Pareto, beta, Chi-square, and bivariate normal

aren’t tested in the Sample Exam P problems. Since Sample Exam P reflects the

Level of knowledge you need to have to pass Exam P, chances are that these

difficult distributions won’t show up in your exam. As a result, you can probably

ignore these distributions
其实P里面需要背什么公式呢？
谢谢！
