I haven't gotten much far yet. Just left it there, thinking that I could use the answer of this as base for other alike questions.

Have you tried sketching the cdf as in part a? This should help you to see what's going on.

Do you not at least know the difference between a "continuous" and a "discrete" probability distribution? That is one of the questions asked that you did not answer.
