the equation would be 15 to the power of b (batters) 5
take the numbers of the people on the team well do 1-15
so do all the possible combinations of jersey 1 at the first batter
then do 2 and so on and so for
so an example could be 1,2,3,4 or 1,2,3,5 and keep doing that but don't repeat
i hope this helps, i can't get the answer it'll take too long but i hope i helped
