Events contain multiple tickets. When you're looping through available tickets using craft.events.tickets.eventId(event.id), you're actually working with a Events_TicketModel. This in turn extends Commerce's Purchasable (opens new window) object.
Outputting a Events_TicketModel object in your template without attaching a property or method will return the ticket’s name:
<h1>{{ ticket }}</h1>
Ticket Models have the following attributes and methods:
The ticket name/title.
The id of the ticket in the system.
