How many different ways can a donor have his or her blood labeled?Answer by neatmath(300)   (Show Source): You can put this solution on YOUR website!This is an example of the counting principle: The Fundamental Counting Principle states that if event M can occur in m ways and event N can occur in n ways, then event M followed by event N can occur in ways. This can be extended to more than 2 events. In this case, we have 3 events: blood type, rh, and gender. So we just need to multiply the number of possibilities for each together: L will stand for the number of possible ways the blood can be labeled. Thus, given our labeling system above, there are 16 different ways a person's blood could be lableled. I hope this helps! :) ******************************************************* Email Scott: neatmath@yahoo.com for help with specific problems, or to inquire about low-cost mathematics tutoring via email or other methods.
