The Fundamental Counting Principle & Tree Diagrams
The Fundamental Counting Principle • If you have 2 events: 1 event can occur m ways and another event can occur n ways, then the number of ways that both can occur is m*n • Event 1 = 4 types of meats • Event 2 = 3 types of bread • How many different types of sandwiches can you make? • 4*3 = 12
3 or more events: • 3 events can occur m, n, & p ways, then the number of ways all three can occur is m*n*p • 4 meats • 3 cheeses • 3 breads • How many different sandwiches can you make? • 4*3*3 = 36 sandwiches
• At a restaurant at Six Flags, you have the choice of 8 different entrees, 2 different salads, 12 different drinks, & 6 different desserts. • How many different dinners (one choice of each) can you choose? • 8*2*12*6= • 1152 different dinners
Fund. Counting Principal with repetition • Georgia license plates have 3 letters followed by 4 #’s. • How many different licenses plates are possible if digits and letters can be repeated? • There are 10 choices for digits and 26 choices for letters. • 26*26*26*10*10= • 175, 760, 000 different plates
Phone numbers • How many different 7 digit phone numbers are possible if the 1 st digit cannot be a 0 or 1? • 8*10*10*10= • 8, 000 different numbers
Tree diagram Flip a coin, then roll a die, list all alternatives
