To perform a certain type of blood analysis, lab technicians must perform two procedures. The first procedure requires either one or two separate steps, and the second procedure requires either one, two, or three steps.

(a)

List the experimental outcomes associated with performing the blood analysis. (Select all that apply.)

If the random variable of interest is the total number of steps required to do the complete analysis (both procedures), show what value the random variable will assume for each of the experimental outcomes. (If an experimental outcome does not occur, enter NONE.)
