I think there is no use case in Visualforce where it could be possible to use a ternary operator (at least all my attempts returned Error: Syntax error).

What you may want to use is an IF Function:

IF(logical_test, value_if_true, value_if_false)

Example:

{!IF(someVariable == 'OK', 'it is ok', 'not ok')}

    I'd go so far as to say that the IF statement is a ternary operator, as it always requires three parameters, and the two branches must return compatible data types in at least most cases, making it identical in behavior with only a 4 character "penalty" over a ?: operator. – sfdcfox Mar 24 '15 at 13:50
