Answer:
1. 45
2. 9
3. 11
4. 17
Explanation:
Given the following:
28 checked H
26 checked C
14 checked D
8 checked H and C
4 checked H and D
3 checked C and D
2 checked all.
Hence N(H) = 28
N(C) = 26
N(D) = 14
N(H U C) = 8
N(H U D) = 4
N(C U D) = 3
N(H U C U D) = 2
We also know that
Total = N(H) + N(C) + N(D) - N(H U C) - N(H U D) - N(C U D) + N(H U C U D)
Substituting the given values, we obtain
Total = 55
1. Students that didn't check any box = 100 - 55 = 45 students
2. Students who checked exactly two box
= N(H U C) + N(H U D) + N(C U D) - 3N(H U C U D) (from probability theorem)
Substituting the values, we have 8 + 4 + 3 - 6 = 9 students
3. Students who checked atleast two box =
The people who have checked all three are needed to be calculated once. Earlier, we subtracted them thrice so we add one time
N(H U C) + N(H U D) + N(C U D) - 2N(H U C U D) = 8 + 4 + 3 - 4 = 11 students
4. Given N(C) = 26
We subtract N(CUD) and N(HUC) as they have checked another apart from club.
26 -8 - 3 = 15
Now we could notice we have subtracted N(HUCUD) twice in both categories, so we add one time to neutralise
15 + 2 = 17
Hence N(only C) = 17 students.

Answer:
The answer to the given question is the option "4".
Explanation:
Icon is a small picture that helps the user to recognize a thing more easily. In computer science, an icon is a small picture or symbol that is used to provide a graphical description of the software program on a computer screen. In this question all other option is not correct that can be described as:
The start menu is a button on the computer. In this button, there are many options or sub buttons. like, documents, pictures, help, and support, control panel, etc. So, it is not an icon.
In the start menu, there is an option of the help and support so it is not an icon.
The background image is also known as wallpaper. So it is not an icon.
That's why the answer to this question is the option "4".
Answer:
D. notifying your employer of all accounts you have access to, and requesting that they change all passwords before you leave
Explanation:
Assuming your employment is terminated, notifying your employer of all accounts you have access to, and requesting that they change all passwords before you leave is a behavior that would not harm a company. In the true and actual sense, making such suggestions is commendable because it would go a long way to cause more good rather than harm the company.
Some mischievous and malicious employees would rather not tell so they can still have an unauthorized access to the company's account and perpetrate various level of evil.
Hence, it is a good global practice to have a company's login credentials updated whenever an employee's employment is terminated.
