What is combination in probability?The discrete mathematics discipline of combinatorics is built on combinations and permutations. There is only counting in combinatorics. Counting appears simple at first glance. Since it was the first type of mathematics learned in school, it is no surprise. It turns out that counting is remarkably non-trivial, and mathematicians are currently working to solve a vast number of open combinatorial problems.

The following are two different images that are encoded using the same algorithm. The images are each in a 5 by 5 grid of pixels where each pixel is black, white, red, green or blue.
The image on the left gets encoded and compressed down to 21 digits while the image on the right gets compressed down to 25 digits. Although the same algorithm was used to encode and compress these images, why are the end results a different length?
a. The algorithm was probably used improperly in the image on the right, causing it to be a longer length than it should have been.
b. Because this is a lossy compression, sometimes information is lost during the compression.
c. The amount of size reduction from compression depends on the amount of redundancy in the original data.
d. The image on the right uses more colored squares and therefore requires more digits to represent the pixels.
Because the degree of redundancy in the original data affects how much space is saved through compression, the final results will vary in length.
What is the pixel definition in a nutshell?The smallest part of a digital display is a pixel. A images or video that is displayed on a device's screen could contain millions of pixels or more. The red, green, and blue (RGB) colors are produced by each of the subpixels that make up a pixel and are displayed in a variety of intensities.
Do more pixels necessarily mean better quality?Images with higher resolutions have clearer, sharper appearances and more pixels per inch (PPI), or pixel information. Less pixels make up low-resolution photographs, and if they do, they tend to be larger.

Maximum likelihood estimation (MLE) is a statistical technique for estimating the parameters of a probability distribution that has been assumed given some observed data. This is accomplished by maximizing a likelihood function to make the observed data as probable as possible given the assumed statistical model.
Why is estimate using maximum likelihood used?
Finding the set of parameters (theta) that maximize the likelihood function, or produce the highest likelihood value, is the goal of maximum likelihood estimation. The conditional probability determined by the likelihood function can be broken down.

An iSCSI target that has been defined someplace on the SAN fabric is where the ISCSI initiator runs. Additionally, you can use this tool to specify CHAP and IPsec security settings for iSCSI.
In Windows Server 2016, how can I establish an iSCSI virtual disk?Choose File and Storage Services from the left pane of Server Manager. Pick iSCSI. Tasks > New iSCSI Virtual Disk can be found on the iSCSI VIRTUAL DISKS panel. Make certain CorpiSCSI is chosen under Server.
How should I set up the Microsoft iSCSI initiator service?Launch the iSCSI initiator from the Control Panel (or run iscsicpl.exe ). Set the automatic startup type for the Microsoft iSCSI Initiator Service in the Service Management console (services.msc) or use this command.

Which of the following wireless communication technologies can be described as follows
1. Has a very limited transmission range, of less than two inches
2. Used with credit cards and passports
3. Slower than other wireless technologies
4. Constantly emitting a signal
NFC
Wireless communication technologies can be described as NFC. NFC stands for Near-Field Communication.
What is Near-Field Communication?
Near-Field Communication (NFC) is a short-range wireless technology that enhances the intelligence of your smartphone, tablet, wearables, payment cards, and other gadgets. The pinnacle of connection is near-field communications.
Whether paying bills, swapping business cards, downloading coupons, or sharing a research paper, NFC allows you to communicate information between devices swiftly and simply with a single touch.
Through the use of electromagnetic radio signals, two devices can communicate with one another through near-field communication. Due to the close proximity of the transactions, both devices must have NFC chips in order for the system to function. Data communication between NFC-enabled devices only happens when they are physically contacting or within a few centimeters of one another.

In the winter, municipal snowplows must plow both sides of city streets that are bidirectional
(two-way traffic) but they only make a single pass over unidirectional (one-way) streets. We can
represent city streets as the edges in a graph using nodes for intersections. Of course, it is a
requirement that every street be plowed appropriately (once in each direction for bidirectional
streets and only once in the proper direction for unidirectional streets). Write a program that
uses integers to represent nodes, and tuples (pairs of integers enclosed in parentheses, e.g., (4
7), to represent a street from node 4 to node 7, and a second tuple, (7 4) to represent the fact
that this is a bidirectional street). Assume that there is but a single snowplow and it must start
and return to node 1. Your program must read a collection of tuples from a file and then
produce driving instructions for the snowplow operator telling the sequence of intersections
(nodes) to visit so that all the streets are appropriately plowed. If it is impossible to perform a
correct plowing (some street would be left unplowed or some street would be plowed twice)
your program must report this fact. Your program should repeatedly read collections of tuples
and processes the information until an end-of-file is encountered. Your program will lose a
significant number of points if your algorithm fails to work properly for cities (graphs)
containing both bidirectional and unidirectional streets.
Your solution must include the data file that it uses for input. Remember NOT to use an
absolute path to access the data file – use a relative path. Be certain your data describes several
different city street situations so that your program can demonstrate that it meets all the
requirements.
Using the knowledge in computational language in python it is possible to write a code that represent city streets as the edges in a graph using nodes for intersections.

in the activity selection problem, if a new activity is added to the input activity set, which has the earliest finishing time among all activities. compare with the solution of the original problem, which of the following are true?
When the list is not sorted, this issue has an O(n log n) complexity. O will be the complexity when the sorted list is provided (n).
What is the problem of activity selection?The goal is to identify a solution set that can execute the most non-conflicting activities possible in a given time frame, assuming that only one human or machine is available for execution. Let's assume that you have n activities with start and finish times. The activity selection problem is a combinatorial optimization problem that involves choosing non-conflicting tasks to complete within a specific amount of time from a set of tasks that are each identified by a start time (si) and finish time (fi).When the list is not sorted, this issue has an O(n log n) complexity. O will be the complexity when the sorted list is provided (n).To learn more about activity selection problem, refer to:
