Each player starts with 2 event, (one random 7 or 9, and one 11 or 12)
You should probably put the unused events back in the box after setup.
I know both the image and the descriptions on pages 2 and 3 may look different or are at best unclear, but on page 5 under buying a new event program it says that players should have 2 event programs, and mentions that only "larger" events can be purchased.
Also the starting ones don't have any prices, so we've assumed they can't be bought!
This is correct. Everyone gets two starting events; one randomly dealt from the 7/9 valued events and one from the 11/12 valued events. If there are less than five players, unused starting event tiles are returned to the box.
