Probability & Statistics/Expert Profile

Ask A Question


I can answer all questions up to, and including, graduate level mathematics. I do not have expertise in statistics (I can answer questions about the mathematical foundations of statistics). I am very much proficient in probability. I am not inclined to answer questions that appear to be homework, nor questions that are not meaningful or advanced in any way.

Experience in the area

I am a PhD educated mathematician working in research at a major university.




Various research journals of mathematics. Various talks & presentations (some short, some long), about either interesting classical material or about research work.


BA mathematics & physics, PhD mathematics from a top 20 US school.

Awards and Honors

Various honors related to grades, various fellowships & scholarships, awards for contributions to mathematics and education at my schools, etc.

Past/Present Clients

In the past, and as my career progresses, I have worked and continue to work as an educator and mentor to students of varying age levels, skill levels, and educational levels.

2017-01-18 Probability question:

This is a very  basic, standard concept. Here's how it works:    First, if you did this one time, the probability of guessing it right is one in five.    We will call that "p" -- so we say p=1/5.    And

2016-12-21 I need help with a 3-part probability problem- please help?:

The key to determining whether the problem is asking you to count combinations or permutations is whether order matters. A permutation accounts for order, while a combination does not. The problem states
