Question 287482
A committee of 5 people is to be selected from student council. Council has 6 boys and 7 girls. What is the probability that the committee will have at least 3 boys? 
I know the answer is 59/143 = .413 
I don't know the steps of how to solve the problem.
---------------------------------------------------------
P(3<= x <=5) = p(x=3) + P(x=4) + P(x=5)
= 6C3/13C3 + 6C4/13C3 + 6C5/13C3 
----------
= [6C3+6C4+6C5]/13C3
------
= [20+15+6]/286
---
= 41/286
= 0.1434
