People visiting video rental stores often rent more than one DVD at a time. The probability distribution for DVD rentals per customer at Video To Go is given in the table below. There is a five-video limit per customer at this store, so nobody ever rents more than five DVDs.
x P(x)0 0.051 0.542 0.243 _____4 0.085 0.04
-Part (a) -Describe the random variable X in words. -X is the number of DVDs a customer rents. -X is the number of times a single customer comes into the store. -X is the number of total DVDs rented at the store. -X is the number of DVDs a customer owns. -X is the number of customers that come into the store. -Part (b) -Find the probability that a customer rents three DVDs. (Enter an exact number as an integer, fraction, or decimal.) -Part (c) -Find the probability that a customer rents at least four DVDs. (Enter an exact number as an integer, fraction, or decimal.) -Part (d) -Find the probability that a customer rents at most two DVDs. (Enter an exact number as an integer, fraction, or decimal.)
