When we calculate the likeliness of the occurrence of one or more events, it is called Probability. It is also the calculation of whether or not a specific situation or condition is correct. Statistics is the collection of data, its analysis, and interpretation. Probability and Statistics Syllabus for GATE form an important part of the exam. If you want to score well in the exam, you must prepare the chapter.

You will find Probability and Statistics GATE questions in both the general aptitude section and the main paper. To start preparing for Probability and Statistics MCQ questions, you must first understand the concepts. When we calculate the likeliness of the occurrence of one or more events, it is called Probability. It is also the calculation of whether or not a specific situation or condition is correct. Statistics is the collection of data, its analysis, and interpretation.

Important Probability and Statistics topics for GATE EE

The Probability and Statistics Syllabus for GATE includes a wide range of topics. For Electrical Engineering, you have to study Conditional Probability and theorems. For statistics, you must prepare to Mean, Median, Mode, Standard Deviation, and Random variables. Along with this, the candidate has to prepare Probability and Statistics GATE notes for Discrete and Continuous distributions, Poisson distribution, Normal distribution.,

  • In statistics, data is divided into two categories, grouped and ungrouped data. Grouped data is available in intervals. When class intervals are unavailable and only observations are present, it is known as ungrouped data. When the data is available at continuous and regular intervals, it is known as closed data.
  • In probability, there are certain events that you must know. (AUB) The means union of two events  (AUB)which means that either or both the events can occur.
  • The intersection of two events (A∩B) means that both the events must occur at the same time.

Topic

Explanation

Formula

Mean

Mean is the average sum of all numbers. 

Mean = sum of observations÷ the number of observations

Median

Median is the middle number when all the numbers are arranged in an ascending or descending manner.

In case of odd numbers

Median= (n+1)th observation÷2

For even numbers

Median= (n/2th observation + (n/2+1th observation)

Mode

Mode is the number with maximum frequency. The number which occurs the most time in a group of numbers is called the mode.

Check the number that occurred the maximum number of times.

Tips and Tricks for Probability and Statistics questions for GATE 

Ensure to keep the following points in mind while solving the Probability and Statistics online test for GATE EE

  • The probability of an event will always range between 0-1. 0 means that the event is impossible. 1 means that the event will definitely occur.
  • When you are required to take out the median in statistics, the first step is to arrange the observations in an ascending or descending order depending upon the question's requirement.
  • Check if there are particular patterns between the data and arrange it accordingly.
  • Attempt as many Probability and Statistics online quizzes as you can before the exam. You can download Probability and Statistics MCQ pdf from various platforms.

Importance of Probability and Statistics Section for GATE 

  • ProbabilityPrpobability and statistics questions are important in GATE exam because it helps in learning the outcomes of situations so that engineers can determine the possibility of failure or success.
  • Statistics help in determining and understanding variability. It helps in production methods.
  • Probability and statistics help in daily life such as weather forecasting, testing a new app or machine.
