Hypergeometric Distribution Question
Hi I can't seem to understand and solve this question. Can someone please help me?
Q: In a math class of 20 students, 5 are bilingual. If the class is randomly divided into 4 teams,
a) what is the probability that a team has fewer than 2 bilingual students?
b) what is the expected number of bilingual students on a team?
A: a) 0.6339
I can't figure out how to deal with the 4 teams. Using the standard hypergeometric formula, I've come up with:
If someone could please show me what to solve this, that would be great.
