Answer:
Option d) ∑f(x) = 1 for all values of x
Step-by-step explanation:
We are given the following information in the question:
f(x) is discrete probability function.
Then, the sum of all the probabilities over all possible values of x is 1.
Thus, we can write:
[tex]\displaystyle\sum_{i=0}^{i=n} f(x_i) = 1\\\\f(x_0) + f(x_1) + ... + f(x _n) = 1[/tex]
Option D) is the correct answer.
Option d) ∑f(x) = 1 for all values of x
