What is the probability that a randomly selected individual will rent at most 3 DVD's ? Answer by ikleyn(52858) (Show Source):
"At most 3" means 0 (zero) OR 1 OR 2 OR 3.
Therefore, the probability under the question is equal
P = P(0) + P(1) + P(2) + P(3).
Substitute the values from the table and calculate.
