We cannot have 0 at the hundred's place for 3-digit number. Number of ways selecting fountain pen = 10. The Fundamental Counting Principle (FCP) To determine the number of different outcomes possible in some complex process: 1. This principle can be used to predict the number of ways of occurrence of any number of finite events. So, we have to use "Addition" to find the total number of ways for selecting the food item. So we have to find all the three digit numbers with distinct digits. The fundamental counting principal can be used in day to day life and is encountered often in probability. Try the given examples, or type in your own problem and check your answer . Solution : Number of ways of selecting Chinese food items = 7 Number of ways of selecting Indian food items = 10 Here a person may choose any one food items, either an Indian or a Chinese food.

That is we have to do all the works. According to the fundamental counting principle, this means there are 3 2 = 6 possible combinations (outcomes). What is the fundamental counting principle example? = (Number of ways in which the 1 st sub event of choosing 0 men from a total 5 can be accomplished) (Number of ways in which the 2 nd sub event of choosing the 4 women from a total 6 can be accomplished) n . Now, there are only 9 ways to fill the thousands place, as 0 cannot be used there. Example 4 Find the number of 4-digit odd numbers formed using the digits 0 to 9 such that repetition of digits is (i) allowed (ii) not allowed Solution The units digit in this case can be filled in 5 ways (using the odd digits). That means 63=18 different single-scoop ice-creams you could order. Let's see a few fundamental counting principle examples to understand this concept better.

Mark is planning a vacation and can choose from 15 different hotels, 6 different rental cars, and 8 different flights. Example 1 - Tree Diagram A new restaurant has opened and they offer lunch combos for $5.00. Fundamental counting principle examples The best way to understand the fundamental counting principle is by applying it to some real-world problems. It says, "If an event can occur in m different ways, following which another event can occur in n different ways, then the total number of occurrence of the events in the given order is mn." This principle can be extended to any finite number of events in the same way. First we are going to take a look at how the fundamental counting principle was derived, by drawing a tree diagram.
