Best ResponseYou've already chosen the best response.1The easiest way to do this is to draw 9 lines and list your options 9 1 1 6 5 4 3 2 1 _ _ _ _ _ _ _ _ _ So we have 9*6*5*4*3*2 different lineups

Best ResponseYou've already chosen the best response.0There are 9 batters. However, 2 are preselected. that leaves 7 batters and 7 slots. there are 7! ways of assigning the 7 batters to the 7 slots.

Best ResponseYou've already chosen the best response.1Ah sorry the first should be a 7 not 9 since the 1 and 1 are already preselected as phi says
