. How many ways are there to split a dozen people into 3 teams, where one team has 2 people, and the other two teams have 5 people each?

1/2!(12, 2)(10, 5)

Step-by-step explanation:

Let's pick 2 persons for team one. We can do that in (12, 2) ways. Then, let's pick five of the remaining people for team two. We can do that im (10, 5) ways. Five remaining people form team three., because the order of teams foes not matter divide the team by 2! (we have 2 teams with five people). Thus the final answer is 1/2!(12, 2)(10, 5)

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
