What Are Good Resources for Understanding Basic Probability Distributions?

AI Thread Summary
Understanding basic probability distributions can be challenging, especially with concepts like Gaussian, Poisson, and discrete distributions. Recommended resources for improving comprehension include Khan Academy, which offers videos and exercises, and the book "Probability and Statistics for Engineers and Scientists" by Sheldon M. Ross. Online courses from platforms like Coursera and edX also provide in-depth learning opportunities. Many users find these resources helpful for grasping the material and addressing topics like error propagation. Utilizing these tools can significantly enhance understanding of probability distributions.

Basically, I'm having some difficulty grasping some of the concepts in probability.

..At first I was writing details of what my lecturer has given me, but really I can't make much sense of it and it'd be foolish to type it all out here.

The jist of work is really just as follows; we've been doing basic work on different kinds of distributions: gaussian, poisson and discrete distributions (how the distributions arise and what they're good for etc) and the notes I'm following are pretty bad, I've got a basic physics textbook but its not really much help in this area since its really just maths and really what I'm asking is does anyone know where I can get some good notes on basic info about distributions and errors (uncorrelated error propagations etc..)?

I've tried googling and I'm finding random stuff that's useful, but yeah.

c'mon..

thanks.

One of the best places to look for help with probability and distributions is Khan Academy. They have a series of videos and interactive exercises on probability, distributions, and errors. Additionally, they have a forum where you can ask questions and get help from other students and experts. Another great resource is the book Probability and Statistics for Engineers and Scientists by Sheldon M. Ross. This book provides an introduction to the concepts and tools for understanding probability and statistics, and it includes numerous examples and exercises. Finally, there are a number of online courses available through MOOCs (Massive Open Online Courses) that can provide a more in-depth look at probability and distributions. Coursera and edX are two of the most popular platforms for these courses.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
