##### Expertise

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.

AMS

##### Publications

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

##### Education/Credentials

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.

#### 2017-02-24 Least Squares Method:

The least-squares method can be used to produce a line-of-best-fit for a set of data. If you are given a line that is a potential best fit, you would find the residual at each data point (the height from

#### 2017-02-07 Probability of not getting a letter in 1000 tries:

This is actually a very tricky question, so let's start with an easier version.    Let's roll a 4-sided die (labeled A, B, C, D) 10 times. Say we want to figure out the probability of getting all four

#### 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

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

#### 2016-10-08 Odds in winning.:

Assuming the payout is the same, then yes, the two games are the same.    Each lottery ticket is (essentially) independent -- they are random, so winning or losing one has no effect on the next ticket
