Please answer the following questions in a Word document:
- Consider the scenario: You have 4 shirts and 5 pants. How many different outfits can you make? Provide at least two other examples where you apply the fundamental counting principle in everyday life.
- Entering a PIN number for an ATM is an example of a permutation because the order in which the digits are entered matters. How is this different from a combination? Provide an example of a permutation and a combination from real life, and explain why each is a permutation or a combination.
- Rolling a pair of dice illustrates an independent event, where the outcome of one die does not affect the other. Provide another example of an independent event and explain why it is independent. Then, define a dependent event, give an example, and explain why it is dependent.
- Sitting at a bus stop bench and riding on a bus exemplify mutually exclusive (non-overlapping) events because both cannot occur simultaneously. Explain why these events are mutually exclusive. Offer at least two more examples of mutually exclusive events and justify why they are mutually exclusive.
- Flipping a coin twice and obtaining heads both times is an example of a probability event. When flipping a coin 1,000 times, it is nearly impossible for all flips to land heads, illustrating the Law of Large Numbers. Provide at least two other real-life examples where the Law of Large Numbers applies.

The principles of probability, combinatorics, and statistical laws play a significant role in understanding real-world scenarios and decision-making processes. The fundamental counting principle, the distinction between permutations and combinations, independent versus dependent events, mutually exclusive events, and the Law of Large Numbers are foundational concepts in probability theory. This paper explores these concepts through practical examples, demonstrating their application in everyday life.
Firstly, considering the scenario of choosing outfits from a wardrobe consisting of 4 shirts and 5 pants, the fundamental counting principle suggests that the total number of unique outfits equals the product of the options for shirts and pants. Applying this principle yields 4 × 5 = 20 possible outfit combinations. This principle extends to many situations, such as selecting meal options from a menu or configuring a computer by choosing among different hardware components. For instance, if a sandwich shop offers 3 types of bread, 4 types of fillings, and 2 kinds of sauces, the total number of sandwich combinations is 3 × 4 × 2 = 24. This demonstrates the utility of the principle in calculating possible variations in daily choices.
Secondly, the difference between permutations and combinations lies in the importance of order. Entering a PIN at an ATM is a permutation because the sequence of digits affects the outcome—1234 is different from 4321. Conversely, selecting three books out of a shelf regardless of order exemplifies a combination, since the set of books selected remains the same whether chosen as {Book A, Book B, Book C} or {Book C, Book A, Book B}. An example of a permutation from life could be assigning distinct tasks to specific days, such as scheduling meetings on Monday, Wednesday, and Friday, where the order affects the schedule. A combination example might involve selecting a team of three players from a group, where the group composition is what matters, not the order of selection. Understanding this distinction aids in calculating probabilities accurately.
Thirdly, rolling a pair of dice illustrates an independent event where the outcome of one die does not influence the other. An alternative example of an independent event is flipping two coins simultaneously; the result of one coin flip does not affect the other. A dependent event, on the other hand, occurs when the outcome of one event influences the probability of another. For instance, drawing two cards sequentially from a deck without replacement is dependent, because the first draw affects the probabilities on the second. If the first card drawn is a king, the probability of drawing a king on the second draw changes, illustrating dependence. Recognizing independent and dependent events is crucial for accurate probabilistic modeling.
Fourthly, sitting at a bus stop bench and riding on a bus are mutually exclusive events because both cannot occur simultaneously—the act of sitting on the bench prevents being on the bus at that moment. Other examples of mutually exclusive events include flipping a coin and getting either heads or tails, but not both; or rolling a die and obtaining either a 3 or a 5, but not both at once. These events are mutually exclusive because the occurrence of one excludes the possibility of the other happening at the same time, which is essential in calculating probabilities where mutually exclusive events are involved.
Finally, the Law of Large Numbers states that as the number of trials increases, the experimental probability approaches the theoretical probability. Flipping a coin twice and resulting in heads both times is plausible, but when performing 1,000 flips, it becomes increasingly unlikely that all flips will land heads, due to the law's implication that relative frequencies stabilize with larger samples. Similarly, in quality control, if a factory produces a large batch of items, the proportion of defective items in the sample tends to approximate the actual defect rate, exemplifying the law. Other applications include estimating the average number of customers visiting a store in a day or predicting the long-term average outcome of a gambling game, both of which rely on large samples to approximate expected probabilities accurately.
