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.

Use the data in the following table, which lists drive-thru order accuracy at popular fast food chains. Assume that orders are randomly selected from those included in the table. Drive-thru Restaurant A B 267 Order Accurate Order Not Accurate 334 237 149 37 52 34 14 If one order is selected, find the probability of getting food that is not from Restaurant A. The probability of getting food that is not from Restaurant A is (Round to three decimal places as needed.)
