Question 1200705
<br>
Interpret the problem differently than the other tutor; it seems to me all 24 students must be formed into groups of 6.<br>
To form the first group, the teacher can choose any 6 of the 24 students; the number of ways to do that is "24 choose 6", C(24,6).<br>
Then there are 18 students left with which to form the second group of 6 -- in C(18,6) ways.<br>
And then C(12,6) ways to form the third group, and finally C(6,6) ways to form the last.  Of course C(6,6) is 1, because with 6 students left there is only one way to form a group of 6.<br>
ANSWER: C(24,6)*C(18,6)*C(12,6)*C(6,6) = ...(large number....)<br>
