Transcript text: State whether the function is a probability mass function or not. If not, explain why not.
\[
f(x)=\frac{1}{14} x, \text { for } x=2,3,4,5
\]
Select all that apply.
A. The function $f(x)$ is a probability mass function.
B. The function $f(x)$ is not a probability mass function because it does not satisfy the third condition of probability mass functions.
C. The function $f(x)$ is not a probability mass function because it does not satisfy the first condition of probability mass functions.
D. The funmtion $f(x)$ is not a probability mass function because it does not satisfy the second condition of probability mass functions.
