I assume you mean "transaction log" when you say "binary log".
It is possible to restore your database if you have a file system backup
of the database in some state before the "DROP DATABASE" command.
Then you could start from there and restore the database to a point
just before the DROP.
If you have no file system backup, there is no way.
