About this course
The Probability for Data Science course begins with introducing you to different concepts in probability. It then continues with inculcating in you the skills to work with marginal probability to solve problems that are events irrespective of the outcome of another value and the Bayes Theorem that deals with the probability of occurrence of events based on the occurrence of other events. You can refer to the attached study materials at any point after enrolling in the course and take up the quiz at the end to test your knowledge and understand your gains.
After completing this free, self-paced, beginner's guide to Probability for Data Science, you can register for top-rated Data Science Courses and embark on your Data Science career with a professional Post Graduate certificate and learn various concepts with millions of aspirants across the globe!
Course outline
Basics of Probability
This section includes answers to questions like what is probability? Why is there a need to learn probability? What are the rules of probability? You shall look at the application of probability later in this section.
Marginal Probability
You will learn about marginal probability and understand its features. The section also solves a problem when the condition is a margin to help you understand the concept better.
Bayes Theorem
The section begins with explaining what Bayes theorem is and then continues with helping you understand the concept with addition and multiplication rules. You will then work with a problem statement and derive a solution to it to understand the concept better.

Probability for Data Science
Probability is a mathematical concept that plays a key role in the field of data science. In data science, probability is used to model and make predictions about uncertain events based on past data. Probability is also used to quantify the likelihood of different outcomes, to make inferences and draw conclusions from data, and to evaluate the reliability of data-driven models.
Probability is a powerful tool for data scientists, as it allows them to model and make predictions about complex and uncertain phenomena. Some of the key use cases and benefits of probability in data science include:
Predictive modeling: Probability is used to build predictive models that can make predictions about future events based on past data. For example, a financial institution may use probability models to predict credit risk or market trends.
Statistical inference: Probability is used to make inferences and draw conclusions from data. For example, a data scientist may use probability models to infer the relationship between different variables, or to estimate the distribution of a population based on a sample of data.
Model evaluation: Probability is used to evaluate the reliability of data-driven models. For example, a data scientist may use probability models to assess the accuracy of a predictive model or to determine the confidence interval of a prediction.
Probability is important in data science because it provides a framework for modeling and predicting uncertain events. Understanding probability is essential for data scientists, as it allows them to make informed decisions based on data and to evaluate the reliability of data-driven models.
In conclusion, probability is a critical component of the field of data science. Whether you are a data scientist, a business analyst, or a student, understanding probability will help you to model and make predictions about complex and uncertain phenomena, to make informed decisions based on data, and to evaluate the reliability of data-driven models. The benefits of probability in data science, including predictive modeling, statistical inference, and model evaluation, make it an important tool for anyone interested in the field of data science.
