Probability Distribution: "you have 'incomplete' distribution function because..."
I have attached the image of the problem.
I just do not understand how to proceed.
The question says you have "incomplete" distribution function because it only works for 0, 1, 2, and 3. To find the probability for 4, I know you need to apply "complement rule" (subtract all probabilities for 0, 1, 2, and 3 from 1). By definition, F(2) = P(X<=2), you need to be able to calculate P(X<=2) with f(x).
But I am very unsure on how to do this correctly. Everything I have tried so far has been wrong.
I do know how to get D and E as long as I can figure out how to get C.
