if its legitimate and not stolen just ask the person you bought it from for password or reset to factory settings and put your own pattern lock and email on it

its brand new and you forgot everything already if you did the google mail password assist then open that if dont know that or didnt do it can try provider for assistance and most lockouts are either 1hr or 24hr

Your problem doesn't make sense. You cannot try the password too often. Try a factory/hard reset.
Google search "reset android tablet"

You could try to factory reset the tablet but that would delete everything you installed and downloaded unless you had everything backed up

The only way to remove this if you don't have it re-registered to your own google account yet is to do a hard reset switch off the tablet in the normal way then switch it back on by holding down the power button and the volume up at the same time and choose factory reset this will unfortunately lose all your data but I'm guessing it wasn't your data anyway lol
