Writing homework is the central part of a student’s life. Not only homework but assignments, tests, and exams also play an essential role. Because it impacts overall performance and results; also, some subjects, like Statistics, take a lot of time to consume. That’s why students search “Can someone do my statistics homework?” online and get expert writers’ help. As it is almost impossible for them to work on other skills.

Statistics writing assignment is a challenging topic. It is a tricky subject to study. Whether you are a genius student or not. Things get harsh as you start writing because it requires a great mindset and advanced mathematical understanding. You need to practice your skills in this topic. You have to work hard day and night to complete the statistics assignment. Or else, you can take online help for good results. In this article, you will read about probability, an essential part of statistics. But before that, let’s understand what statistics is.

How Well Do You Know about Statistics?

Statistics is the combined concept of science and mathematics. Generally, it is a measurement of the data. Moreover, it is about collection, review, drawing, description, analysis, and conclusion.

There are two major areas of statistics: descriptive and inferential. The first has a central tendency, such as mean, median, and mode. The second one is about the larger groups. It shows probability and prediction.

However, it is a crucial part of the system. Statistics show the average numerical measurement of the data.

Above all, it is used in all scientific activities such as physical, social science, business, humanities, government, and manufacturing programs. Some students find understanding and writing homework challenging, so they get help from homework writing services. Moving to the next section, where you will read about probability basics.

Basics of Probability and Definitions

Probability is a mathematical theory. Most importantly, it tells about how likely an incident will occur. In other words, it is the chance of the event happening. It is always between 0 and 1. The 0 shows impossibility, and one shows possibility. Overall, it is a numerical concept.

There are some basics of probability theory. Those students who find it tedious to complete can get online help by searching for statistics homework help.

Random Experiment 

It is a trial process. Therefore, you can repeat it many times to get a set of better outcomes. For example, tossing a coin.

Sample Space

It is nothing but a result of a random experiment. In other words, it is a possible outcome of an experiment. For example, Head and tails (for tossing a coin).


An experiment forms a set of sample spaces. In probability theory, a subset of a sample space is called an event. There are a few types of events in this theory.

  • Independent events

They are freely conducted events. They don’t rely upon other events.

  • Dependant event

They depend on other events

  • Mutually exclusive events

Events that can not take place together.

  • Equally likely event

It means two or more events have the same chance of occurring.

  • Exhaustive events

This is equal to a sample space event.

Random variables 

A random variable means an assumed value of all possible outcomes of an experiment.

There are two types of random variables.

  • Discrete random variables

It is an exact value such as 0,1,2.

  • Continuous random variables

There are an infinite number of values. There are two main factors: cumulative distribution function and probability density.


As already said, probability shows the numerical possibility of an event occurring. It can be between 0 and 1.


It is a term that shows how the distribution of a random variable varies for the mean. Moreover, it is a measure of dispersion.


An average value of the total outcomes of an experiment occurring multiple times is called expectation. It is also known as the mean of the random.

Probability Distribution

It is a combination of three basics. It shows the measurement of all possible values of an experiment.

Probability mass function

It shows a value equal to a discrete random variable.

Probability density function

It is a possible value of continuous random variables.

Joint probability distribution

It is a probability distribution of all possible outputs. Also, you can consider it for any given number of variables.

Conditional probability distribution 

It can be observed after the realization of another variable. In short, it is the probability distribution of a random variable.


Generally, writing statistics assignments is a challenging job. Hence, getting online help is the best way. So, search ” Can someone do my statistics homework?” and get the best services because it helps you learn the basics of probability, along with definitions, examples, and formulas. It makes the statistics course simpler and better for you.
