There is a special calculator that when adding numbers rounds the number to the closest integer. For example, 1.1 + 2 + 3.6 will be calculated as 1 + 2 + 4. The error from each addition follows a uniform distribution of (-0.5, 0.5).
a. When 1500 numbers are added, what is the probability that the absolute value of the total error is greater than 15?
b. How many numbers can be added until the probability of the absolute value of the total error being less than 10 is equal to 0.9?
Please thoroughly explain where each equation comes from and how to work the problem!

There is a special calculator that when used to add numbers up,
it always rounds up or down the number to the closest integer and
ignore the decimals. For example, you want to add 1.1+2+3.6, it
will show can calculate as 1+2+4, etc. Assume the error from each
adding follows uniform distribution on (-0.5, 0.5).
When adding 1500 numbers together, what is the probability of
the absolute value of total error is greater than 15?

Write a Java program to convert decimal (integer) numbers into
their octal number (integer) equivalents. The input to the program
will be a single non-negative integer number. If the number is less
than or equal to 2097151, convert the number to its octal
equivalent.
If the number is larger than 2097151, output the phrase “UNABLE

A zombie picks up a calculator and starts adding odd whole
numbers together, in order: 1 + 3 + 5......etc. You want to be able
to determine the last number the zombie will add that will make the
sum exceed some target number, such as "What will be the last
number added that will make the sum on his calculator greater than
10,000?".
Write the MATLAB code necessary to solve this problem for the
zombie or he will eat your...
