Note: Here, in this question, it is not mentioned the x follow which distribution. But f(x) is equal to 1/5 over the range 3 to 8. So, by logically, we can assume that that the x follow continuous uniform distribution because if you integrate f(x) over the range 3 to 8 then you will get the value 1.
