Work through a solved example with mutually exclusive and exhaustive events A, B, and C; use union probability equals one and inclusion-exclusion to determine P(A) = 4/13.
Apply Bayes' rule to compute P(B|A) with 0.001 prevalence, 0.999 test positive given TB, and 0.002 test positive given no TB; the result is 0.333.
Four testers independently rank three brands A, B, and C at random. We compute the probability that chocolate E’s total score equals four by summing the four independent ranks.
Graph the density on [3,5] and verify its area equals one. Compute probabilities by integration, including x ≤ 4, 3.5 ≤ x ≤ 4.5, and x > 4.5.
This course is the key to learn how to crack statistics questions. It has students from over 100 countries and here is what some of them have to say about this Statistics course:
I already knew the basics of these concepts but I was struggling with the questions. This course has very well explained solutions - Ananya Nath
This is my third course with this instructor. He saved my Statistics exam. Big thank you! - Vidit Kumar
Well explained, step by step - Francisco Sanchez
The sole purpose of this course is to make you feel more confident in solving statistics questions by showing you the approaches involved in a simple and step by step manner.
This statistics course has step by step solutions to help you get into the flow of cracking statistics questions related to the following concepts:
Basics of Permutations and Combinations
Probability (Sample space and events)
Probability (Axioms and Properties)
Conditional Probability and Bayes' Theorem
Probability: Independent Events
Probability Distributions for Discrete Random Variables
Expected Values for Discrete Random Variables
The Binomial Probability Distribution
Probability Density Function for Continuous Random Variables
Cumulative Distribution Functions and Expected Values for Continuous Random Variables
Uniform Distribution
Normal Distribution
This course is apt for students who already have basic understanding of these topics and are looking for some solved questions to practice along and to fill in the understanding gaps.
All that said, if you would like to discuss something while you are learning, please feel free to start a discussion or PM me. I would be happy to help.
