I'm trying to write a query that returns the same result from three different events, but I think I am doing it wrong. I can run my query against one event ID and it works. How can I select all three? Here's what I have so far:

SELECT * FROM `Registrations` 
WHERE `Role` = "Attendee" AND `RegistrationStatus_ID` = "1" AND `DigSignature` IS NULL
    AND `Event_ID` = "147" OR `Event_ID` = "155" OR `Event_ID` = "160"
