The accompanying table lists the outcomes and the cumulative probability distribution for a student renting videos during the week while on campus.

Video Rentals per Week during Semester

Outcome (number of weekly video rentals)	0	1	2	3	4	5	6
Probability distribution	0.05	0.55	0.25	0.05	0.07	0.02	0.01

Calculate the cumulative probability distribution for the above table. What is the probability of the student renting between 2 and 4 a week? Of less than 3 a week?
