You and nine of your friends got tickets to a Rockies game. Go Rockies!! Your seats are right behind home plate.
1) How many different ways are there for the 10 of you to sit?
2) Everyone gets thirsty, but no one wants to get up and get a soda. Collectively, you decide that each time you need something, you'll send two people. How many different groups of 2 can you choose from?
3) If 6 trips need to be made for the necessities (drinks, hot dogs, crackerjacks, nachos, popcorn, and cotton candy), what is the probability that you will have to make a group trip during the game?
