I'm a college CS grad who picks up freelance jobs when I have enough room in my schedule. Lately, in my spare time, I've been creating AI software applications on different platforms and drinking lots of milk. 1% only.

This makes sense, thanks for the quick answer. I'll go back over my notes and rework it.

@Alex Don't know Latex, feel free to help out on the edit. Got a handy FAQ section or link with the latex formatting tips?

comment Mary can answer 20/25 problems correct… simple probability
Thanks for taking the time to answer my follow-ups, I know once you start using the shortcuts it's difficult to go back, I appreciate you answering in a way I could easily understand. :)

comment Mary can answer 20/25 problems correct… simple probability
I see, so instead of 10/20 it should have been 20/25, then 19/24, etc for each correctly answered problem? At the time this answer was jotted up, we hadn't done combinations, and I wanted to see what I had done wrong in my thought process, since that will hopefully correlate correctly when we start using combinations more.

comment String probability (with conditional prob and combinations)
This definitely helps clarify for Q1 for the first bolded assumption. Thanks very much for taking the time to explain fully. If you could help me with the others, I'd greatly appreciate it! :)

comment Mary can answer 20/25 problems correct… simple probability
I appreciate the effort, but we're not quite to hypergeometrics yet, could you perhaps explain what about my answer (using the way it was formatted) was incorrect? I'd like to learn from my mistake.

comment Mary can answer 20/25 problems correct… simple probability
I didn't really know which should be used regarding 20/25 or 10/20, wasn't sure it would make a difference... :-/

comment String probability (with conditional prob and combinations)
Thanks for the effort on the first one, could you explain it using combinations as I did so I can understand exactly where I went wrong? That would be great. An answer alone for the second doesn't do me much good though since I got it wrong and don't know how to find the 1/25 probability. :( I'm really looking to learn from my mistakes.

+1 for explaining Xoff's answer a bit more clearly.

Strange, I must have done something wrong (again) calculating the combinations out. Apologies and thanks again! I'll remove my first comment to avoid confusion from others who may view this in the future.

See Byron's answer for what I was looking for. His answer not only explains that my calculation needed to be divided by two, but it shows how to correctly find the number of ways to select at least one bird of each species. I gave you a +1 for effort though, I appreciate your time and the attempt.

comment Probability - multinomial partitioning
Dividing the whole thing by 2 isn't telling me anything I don't already know, I know my calculation is off by 1/2. I'm trying to figure out the error in my logic that led to me having to divide by 2. Dividing by 2 should not be necessary in a problem like this, you should be able to do the calculation and get a correct answer for the number of ways to select at least one of each species.

comment Probability - multinomial partitioning
Sorry, still not getting it. What do I need to change in my computation to make it correct? That may help me to understand the logic behind my error.

comment Probability - multinomial partitioning
Why does it contain two birds when I'm only choosing one of each species? I'm not following your logic. I select one of each species and then select one from the leftover 95 birds... what do I need to change in my computation to make it correct?
