Counting Principal Warm-up (IN) Learning Objective: To use the counting principal to determine numbers of arrangements. You draw a card from a standard deck, find the following probabilities: 1.P(6) 2.P(face card) 3.P(spade) 4.P(king and diamond) 5.P(six or four)

Learning Objective: To use the counting principal to determine numbers of arrangements. Notes Ex 1 – How many ways can 5 students fill offices for the sophomore class: president, VP, secretary, treasurer and historian. pres vp sec treas his = 120 Ex 2 – How many ways can we arrange the students in this class?

Learning Objective: To use the counting principal to determine numbers of arrangements. Ex 3 – all of your clothes are dirty except 2 pairs of pants and 3 shirts. How many different outfits can you put together? a.Make a tree diagram b.Use the Fundamental Counting Principle 2 * 3 = 3

Learning Objective: To use the counting principal to determine numbers of arrangements. Ex 4 – At a sandwich shop, there are 4 breads to choose from, 3 cheeses, 6 meats and 10 veggies. How many different sandwiches can you make? 4 * 3 = 720 * 6 * 10
