Expert Solution & Answer
Chapter 10, Problem 1SA
Explanation of Solution
Encapsulation:
- • It combines the data and code into a single object.
- • It helps in restricting access to the methods.
- • This helps in preventing the data from being modified due to accident.
- • The object’s variable is not directly accessible.
- • Underscore helps in preventing the data from being accessed directly.
The encapsulation rules in python can be summarized as follows:
| Public method | It is accessible from anywhere. |
| Public variables | It can be accessed from anywhere. |
| Private method | It can be accessed only in their own class. |
| Private method | It is accessible only in their class or method. |
- • It protects the data from being tampered. By declaring the data field as private, direct modifications of properties are prevented.
- • It makes the class easy to maintain and reduces the errors...

The warranty states that if the device fails during its first year of use, you get a new device for no cost, and this new device carries exactly the same warranty. However, if it fails after the first year of use, the warranty is of no value. You plan to use this device for the next six years. Therefore, any time the device fails outside its warranty period, you will pay $300 for another device of the same kind. (We assume the price does not increase during the six-year period.) The time until failure for a device is gamma distributed with parameters α = 2 and β = 0.5. (This implies a mean of one year.) Use @RISK to simulate the six-year period. Include as outputs (1) your total cost, (2) the number of failures during the warranty period, and (3) the number of devices you own during the six-year period. Your expected total cost to the nearest $100 is _________,…arrow_forward
