Directions: Construct the probability distribution for the random variables described in each of the following situations. Draw the corresponding histogram for each probability distribution.

1. Suppose three cell phones are tested at random where D represent the defective cell phone and N represent the non-defective cell phone. Let X represents the number of defective cell phones that occur., show the values of the random variable X.

2. Two balls are drawn in succession without replacement from an urn containing 5 red balls and 6 blue balls. Let Z be the random variable representing the number of blue balls. Find the values of the random variable Z.
