H. W 2: A class includes 20 female students and 30 male students, including 15 female students and 20 male students with black hair. If a person is randomly chosen from the class, what is the probability that the chosen person is a female student with black hair? Hint: (Female student with black hair ) = P(AU B)
Answer:
The probability that the chosen person is a female student with black hair is 15/50, or 3/10.

public static void main(String[] args)
{
Scanner keyboard = new Scanner(System.in);
int userNum, val;
final int MIN = 1;
final int MAX = 20;
final int TIME_WASTER = 100000;
System.out.print("Enter a number between " + MIN +
" and " + MAX + " >> ");
userNum = keyboard.nextInt();
while(userNum < MIN && userNum < MAX)

userNum = keyboard.nextInt();
}
for(val = userNum; val == 0; --val)
{
System.out.print(val + " ");
for(int x = 0; x < TIME_WASTER; ++x)
for(int y = 0; y < TIMEWASTER; ++y)
for(int z = 0; z < TIME_WASTER;);
// Adjust these numbers for faster or slower performance
}
System.out.println("Blastoff!");
}
}
program to take the command line input to cut down the blast off.

Using An assembly code
Read a 3 digit number from one row, then a 1 digit number from the second row. Subtract the 1 digit number from the 3 digit number, and display the result. Make sure you print your name first, then your output.
Sample Input
123
1
Output
Name Last name
122
Sample Input
100
1
Output
Name Last name
099 (or you can display 99 without the 0, either one is fine)
Sample Input
001

Output
Name Last name
0 (or you can display 000, either one is fine by me)

You have just purchased a new Dell PowerEdge R820 Rack Server. The server is equipped with four Xeon E5-4650 CPUs, 128 GB of RAM, four 1 TB SAS hard drives, and two 750-watt power supplies. You have a 21-inch LCD monitor connected to your server. You want a UPS to keep your server running for up to 20 minutes in the event of a power failure. You prefer a rackmounted solution. Use the UPS selector tool at APC's Web site (a well-known UPS vendor). The UPS selector is at https://www.apc.com/shop/us/en/tools/ups_selector/
Determine which model of UPS will work well for this server, and state your reasons. Write a one-page memo explaining your choice and why this would work for the above situation. Upload the document here.
Answer:
To: Management
From: [Your Name]
Subject: UPS Recommendation for Dell PowerEdge R820 Rack Server
This memo is to recommend a UPS solution for the Dell PowerEdge R820 Rack Server. After considering the specs of the server and the desired use, I recommend the APC Smart-UPS RT 8000VA RM XL3U.
The Smart-UPS RT 8000VA RM XL3U is a rack mounted UPS designed for large applications. It has an output of 8000VA/5600W and can provide battery backup for up to 20 minutes. It has eight output receptacles, which should be enough to power the server, monitor, and any other peripherals that may be connected. The UPS also has a built-in web/network management interface, which allows you to monitor the UPS and its connected loads, as well as control the UPS remotely.
In addition, the Smart-UPS RT 8000VA RM XL3U can be configured with an optional external battery pack, which can provide up to 90 minutes of backup power. This is ideal for situations where an extended period of time without power is expected, such as during a blackout.
Overall, the Smart-UPS RT 8000VA RM XL3U is an excellent choice for the Dell PowerEdge R820 Rack Server. It is a powerful, reliable, and feature-rich UPS that can provide up to 20 minutes of battery backup and can be configured with an external battery pack for extended backup times.
If you have any questions or concerns about this recommendation, please do not hesitate to contact me.

Sort the school supplies alphabetically. (Be sure to select cells A5:H14 to sort the entire row of data.) Your spreadsheet should look similar to figure below
[ Every time I try sorting it I keep getting a "#DIV/0!" error. I highlighted it in red.
I'm not sure how to fix it this error, I tried sorting each cell in Microsoft Excel separately but it keeps affecting the other ones, like "% of grand total." At the end next to “Oct. cost” For example, and it keeps changing all the numbers and giving incorrect ones. If anyone has a solution to fix it so I can get it to look like exactly like the picture shown below, that would be great! ]
When you get the "#DIV/0!" error, you are attempting to divide an integer by 0. Make sure the denominator (the number you are dividing by) is not zero to correct this mistake.
What does it imply when you get the answer "Div 0" while you're trying to divide by 0?When you divide a number by zero in Microsoft Excel, you get the #DIV/0! error (0). That happens when you type a simple formula, like =5/0, or when a formula refers to a cell that has a value of 0 or is empty, as shown in this image.
If the formula is attempting to divide by zero, what is the error?When a formula tries to divide by zero or a value equivalent, it produces the #DIV/0! error.
