问题如下:
X is a discrete random variable with possible outcomes X = {1,2,3,4}. Three functions f(x), g(x), and h (x) are proposed to describe the probabilities of the outcomes in X.
The conditions for a probability function are satisfied by:
选项:
A.f(x).
B.g(x).
C.h(x)
解释:
B is correct.
The function g(x) satisfies the conditions of a probability function. All of the values of g(x) are between 0 and 1, and the values of g(x) all sum to 1.
老师您好,看您的解答弄懂了问题,请问g(x)和h(x)分别代表什么呢?请问在那个章节可以去学习这两个知识点呢?
