# Probability Tutorial for Data Scientists

## Overview of Probability Tutorial

There is not even a single day in your life when you don’t think about using probability and statistics. Deciding between two options, making predictions, learning weather forecasts, and creating hypotheses are all important aspects of probability. Our daily routines revolve around probability, and statistics is the next significant discipline that governs and determines much of our probable results. Probability and statistics are related yet independent fields.

Statistical Analysis uses probability distributions and theories to make any data calculations and present it via graphs, charts, and pictographs. The two disciplines are learned together to receive meaningful and relevant output in a business. They can serve many purposes from analyzing huge volumes of data, and organizing it to present it in the simplest graphical manner.

Whether you belong to the field of Data Science, Big data Analysis, or Business Intelligence, learning statistics and probability can be of great help to improve business performance, handle and exhibit the data available and apply various logical algorithms, functions, and methods on that data.

Check out our blog for a detailed comparison of Data Mining and Statistics.

In this tutorial, we will cover a range of topics that are going to refurbish your mathematics, statistics and probability knowledge from school and college times.  Further, individuals and statisticians who are willing to enhance The topics include descriptive statistics that will describe varying data through various distributions. You will also get familiar with grouped frequencies, graphical descriptions, probability distributions of discrete and continuous variables, The Normal Distribute (most important of all distributions) and Sampling and Combination of variables.

Most topics here contain explanations relating to mathematical interest to keep up your attention and concentration towards learning. As we say, science, technology and mathematics are directly proportional to practice and practical implementation, each topic in this learning reference is thoroughly explained using real-time examples, which are easy-to-comprehend and memorize.

After learning through this Probability tutorial, you can also enroll in our Data Science courses. These courses are excellently descriptive and provide deeper insights into significant topics, which can be implemented in real-time projects in your organization.

Faq's on Probability Tutorial
Are probability and possibility the same?

No, Probability and possibility are two different concepts. Probability is a measure of how likely an event is to occur, while possibility is a measure of whether an event can occur at all. For example, it is possible to win the lottery, but the probability of winning is very low.

Are probability and statistics the same?

No, probability and statistics are not the same. Probability is a branch of mathematics that deals with the likelihood of events, while statistics is a field of study that deals with the collection, analysis, interpretation, and presentation of data.

Can the probability be negative?

No, probability cannot be negative. Probability is a number between 0 and 1, inclusive.

Can the probability be zero?

Yes, the probability can be zero. An event with probability 0 is an event that will never occur.

Can probability density be greater than 1?

No, the probability density cannot be greater than 1. The probability density is a measure of how likely an event is to occur in a specific region, and it is always less than or equal to 1.

What values can probability take?

The value of probability can range from zero to one, both inclusive.

How can probability be expressed?

Probability can be expressed in a number of ways, including as a fraction, a decimal, or a percentage.

What is the role of probability in machine learning?

Probability is a fundamental concept in machine learning. Machine learning algorithms use probability to make predictions about the future, and they also use probability to evaluate the accuracy of their predictions. For example, a machine learning algorithm might be used to predict whether a customer will click on an ad, and it would use probability to calculate the likelihood of each possible outcome.
