Correct assumption, but not the answer

Yes, we are looking at an instantaneous event--the beginning of an eruption, not an event with duration.

And your answer of 6/11, 3/11 and 2/11 would be right if the eruptions occurred at random, ON AVERAGE every 2, 4, and 6 hours, but surprisingly, the answer is different with the fixed spacing. Without giving away too much, geyser A is somewhat more likely, and both the others less likely to be seen first with the fixed spacing.
