[理工] [機率]-聯合機率分佈
The joint probability density function p(x,x') of two uncorrelated random
variables X and its time derivative X' is given by

Based on this density function, obtain the probability P(A∩B) of the joint
event A and B, that is defined by A=(x<a) and B=[x'dt > (a-x)], with a
positive constant a and the differential time dt.
以上是令小弟百思不解,想到頭快炸掉的恐怖題目......
似乎跨了不少工程機率的章節......
看似都是眼熟的概念,卻不知如何下手(特別是B的部份很詭異......)
懇請善心人士指點迷津,引導解題切入
拜託了!謝謝!
