Delivery truck is required to make five stops on its morning route. Let X denote # of on-time deliveries for a given morning, let f denote probability mass function of X, and let F denote the cumulative distribution function of X. Historical data suggests that:
f_X (5) = 0.88, f_X (4) = 0.06, f_X (3) = 0.03, f_X (2) = 0.02, f_X (1) = 0.008, f_X (0) = 0.002
1. Construct cumulative distribution function of X.
2. Determine probability that truck makes at least 4 on-time deliveries.
Any help or advice on how to start solving this problem would be great. My professor is not great at explaining and most of the class is lost in this subject.
