If a jury of 12 people is to be selected randomly from a pool of 15 potential jurors, and the jury pool consists of 2/3 men and 1/3 women, what is the probability that the jury will comprise at least 2/3 men?

12 people = 8M+4F
Selecting from 15 people.

Well, the question is insufficient. How many are male/female among potential jurors?

the pool is 2/3 men and 1/3 women, so it's 10 men and 5 women.
