<PRE><B>Question 1038337</B>

Probability-and-statistics/1038337 (2016-06-16 03:04:19): There are 24 9th and 10th graders signed up for after school tutoring. Thirteen of them are going to be chosen randomly to be team leaders. 
What is the probability that all 6 chosen are boys? 
-----
You need to know how many boys there are
If # of boys is &quot;b&quot;,
Then # of girls is &quot;24-b&quot;
-----
The p(choose 6 boys) = bC6/24C6
