In the process of producing electric cables for household, an electrical and electronics engineer discovered that the diameter of an electric cable obeyed a continuous random distribution with the following distribution: f(x) = 2(x-1), 0 < x < 2. What does the above imply?
1) The diameter of electric cables is normally distributed.
2) The diameter of electric cables follows a uniform distribution.
3) The diameter of electric cables follows a exponential distribution.
4) The diameter of electric cables follows a triangular distribution.
