Multivariate Hypergeometric Distribution

Click For Summary
SUMMARY

The discussion centers on solving a problem related to the Multivariate Hypergeometric Distribution. The user initially struggled with part B of their homework but later realized their original solution was correct after receiving feedback. Key points include the importance of considering specific cases such as (2,2,0,0) and (0,2,0,2) when applying the distribution. The conversation highlights the need for clarity in problem presentation, as the original post's format was difficult for others to read.

Homework Statement

I worked out A) just fine it seems (given the answer in the book), but B) I'm not sure how to take this out. Below was a try but I'm not sure i was even on the right track. Any ideas?

Anyone have any ideas here?
 
really, with over 400 views? no know can tackle this? Even Reddit at least took a shot at it. come on boys! lol, anything to get me started thinking right about this would help!

In (b) you seem to have forgotten the cases (2,2,0,0), (0,2,0,2) and (2,0,0 2). Otherwise the basics are OK (but please in future try to attach more readable files: yours is incomprehensible on my laptop and on my i-phone; it shows up only on my desktop machine.)

"All nationalities but Italian are represented" So those three do not comply. It must have a zero for the third space, and contain at least one from each of the others, and must equal 4.

ok, I answered my own question. the last two i added in would not work due to the criteria. so i guess you helped, thanks RGV. I'll try and find a better format to post these in.

Sorry, I mis-read question (b). Your original solution is correct, and did not leave anything out (as I had erroneously suggested).

Thanks for looking at it regardless! This site has helped me so much, I appreciate anyone's input!
