Taking continuous probability over discrete probability?

Click For Summary

Discussion Overview

The discussion revolves around the decision of whether to take an upper-level probability course (MATH 471) without completing the elementary probability course (MATH 371) first. Participants explore the implications of skipping the foundational course, considering the content overlap and the importance of both courses in understanding probability theory, particularly in relation to applications in physics and engineering.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • One participant notes that MATH 471 builds on concepts from MATH 371, suggesting that important topics such as probability distributions and combinatorics are covered in the elementary course.
  • Another participant emphasizes the redundancy of concepts between the two courses for undergraduate studies, indicating that MATH 471 may include most of the material from MATH 371.
  • A suggestion is made to consult with instructors or the department chair to better understand the course sequence and its relevance to the participant's goals.
  • One participant mentions that graduate coursework introduces measure theory, which integrates both discrete and continuous probability, highlighting a difference in approach compared to undergraduate courses.
  • A later reply expresses concern about potentially forgetting Calculus IV by the time the participant takes the upper-level course after completing the elementary course.

Areas of Agreement / Disagreement

Participants express differing views on whether it is advisable to skip MATH 371 in favor of MATH 471. Some argue for the necessity of taking both courses, while others suggest that MATH 471 may suffice on its own. The discussion remains unresolved regarding the best course of action.

Contextual Notes

Participants highlight the importance of foundational knowledge in probability theory and the potential gaps that may arise from skipping the elementary course. There is an acknowledgment of the differences in content and approach between undergraduate and graduate-level courses, but no consensus on the necessity of taking both courses exists.

I'm considering taking the upper-level probability course at my school over the elementary course offered because of time constraints. The latter is not a prerequisite for the former. Do you think I will be alright taking the more advanced probability course over the elementary course? Any input offered will be much appreciated. Thank you.

MATH 371 Elementary Probability Theory (3) Sets, discrete sample spaces, problems in combinatorial probability, random variables, mathematical expectations, classical distributions, applications. Pre: [Calculus II]

MATH 471 Probability (3) Probability spaces, random variables, distributions, expectations, moment-generating and characteristic functions, limit theorems. Continuous probability emphasized. Pre: [Calculus IV]

Here are the courses. I've already taken Calculus IV, so I can just skip to 471.

Most of the concepts in MATH 371 are baked into MATH 471 because continuous probability theory is built up in a similar way to discrete prob theory. However, if you just took 471, some of the stuff you'd miss out on learning include important probability distributions and combinatorics, which is by the way very important in statistical physics, computer science etc.

That said, I'd put priority on taking both 371 and 471. If you want to do 471, you'll have to learn most of what's in 371 anyway, so might as well do it properly and take both courses. Also, understanding statistics and probability theory is extremely useful for physicists/engineers.

My suggestion would be to speak to the instructors for both courses if possible (or the chair of the math department) and get their assessment of which sequence of probability courses are worth taking before taking any action.

That being said, from the limited description above, it does seem like MATH 471 would include most of the concepts taught in MATH 371. So you might be OK with taking just MATH 471, but taking both may be a better idea.
 
Hey Eclair_de_XII

For undergraduate courses, most of the concepts are redundant between the two categories of distributions.

For graduate coursework, you learn how to deal with both when you look at measure theory and probability.

You should know this if you want to choose one course over another - and the main difference for undergraduate courses is that you will see Sigma's instead of integrals and different probability transform/generation functions for the discrete and continuous cases.
 
Thank you, everyone. I ended up deciding to take 371 and its supplementary course first, and then 471 and that supplementary course one year later. I'm kind of worried that I might forget my Calculus IV by then...
