I have 2 problems that I can't figure out!
A school of 100 fish is to be tagged with 6 tags:
1. what is the probability of each outcome when each fish may receive any number of tags and there are 2 sets of 3 tags where tags within a set cannot be distinguished from each other?
2. what is the probability of each outcome when each fish may receive at most 1 tag and there are 2 sets of 3 tags where tags within a set cannot be distinguished from each other?
Help! (answers with explanations are best!) Thanks!
