This will be involving selecting balls from a box of numbered balls. Assume that the box contains balls numbered from 1 through 28, and that 3 are selected. A random variable X is defined as 2 times the number of odd balls selected, plus 3 times the number of even. A. How many different values are possible for the random variable X? (ANSWER: 4) B. Fill in the table below to complete the probability density function. Be certain to list the values of X in ascending order.
