The Thunderbolts are coached by Coach Loudvoice. The Thunderbolts have 15 players, but two of them, Alice and Zen, refuse to play together. How many starting lineups (of 6 players) can Coach Loudvoice make, if the starting lineup can't contain both Alice and Zen? (The order of the 6 players in the lineup does not matter; that is, two lineups are the same if they consist of the same 6 players.)
