The question I am working on is:
A Little League team that has 15 players on its roster.
a.How many ways are there to select 9 players for the starting lineup?
b.How many ways are there to select 9 players for the starting lineup and a batting order for the 9 starters?
c. Suppose 5 of the 15 players are left-handed. How many ways are there to select 3 left-handed outfielders and have all 6 other positions occupied by right-handed players?
First of all, what specifically is a starting line-up? and would the order be pertinent or impertinent? How about for batting order? Obviously the name sort of implies that order matters; however, I don't want to presume anything.
