Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
Counting Theory
The fundamental counting principle is a rule that is used to count the total number of possible outcomes in a given situation.

Transcribed Image Text:### Graph Analysis of a Company's Profit
The depicted graph showcases the company's profit \( P(t) \) over a span of 27 months, with profit measured in dollars and \( t \) representing time in months.
#### Graph Description:
- The x-axis (horizontal axis) denotes the time in months, labeled \( 0 \) to \( 27 \) in increments of 3.
- The y-axis (vertical axis) represents the profit in dollars, ranging from 0 to 1100 in increments of 100.
#### Observations:
1. **Initial Phase (0 to 3 months):**
The profit starts at 1100 dollars at month 0 and exhibits a sharp decline, reaching around 700 dollars by the 3rd month.
2. **Subsequent Decline (3 to 9 months):**
The declining trend continues as the profit decreases steadily, lowering to approximately 500 dollars by the 9th month.
3. **Gradual Reduction (9 to 15 months):**
From the 9th to the 15th month, the profit experiences a more gradual decline, settling around 150 dollars by month 15.
4. **Slight Recovery (15 to 18 months):**
Between months 15 to 18, there is a minor recovery with the profit increasing slightly to around 300 dollars.
5. **Further Decline and Fluctuations (18 to 27 months):**
After the brief recovery, the profit continues to drop, reaching its minimum of around 100 dollars by the 21st month. Post the 21st month, the profit fluctuates slightly upwards but generally remains low.
### Conclusion:
The company's profit demonstrates a steep initial decline, followed by a gradual reduction, a minor recovery, and then fluctuating at lower values towards the end of the 27-month period. Analyzing such trends can assist in understanding the factors contributing to profit variations and aid in strategic planning for future profitability.
### Exercises:
Complete parts a through e below, referencing the information from the graph to answer each part effectively.
This graphical analysis helps students learn how to interpret profit trends over time and the implications such trends can have on business decisions.
