Suppose Nancy has classes three days a week. She attends classes three days a week 80% of the time, two days 15% of the time, one day 4% of the time, and no days 1% of the time. Suppose one week is randomly selected. Construct a probability distribution table (called a PDF table) in your draft paper. The table should have two columns labeled x and P00. Then, use the table to calculate the expected value of Nancy's attendance. Note that E = 2 m . P(a:). It means to multiply each x with its P(x) and then add up the values. (Enter an exact number as a decimal.) ,1 X
