Sorry for so silly doubt , but didn’t understand solution of below problem.
Q. How many ways are there to split a dozen people into 3 teams, where all three teams have 4 people each?
As per my understanding , 1st team can be selected in 12C4 ways.
2nd team in 8C4 and 3rd in 4C4
12C4 * 8C4 * 1
Why would you divide it by 3!
