Answer
Unlikely.
Work Step by Step
We know that $probability=\frac{number \ of \ good \ outcomes}{number\ of\ all\ outcomes}$. Therefore $probability=\frac{8}{8+492+306}≈0.009<0.05$. The outcome is unlikely if it's probability is less than 0.05. Therefore it is unlikely. This can be because from middle seats you cannot really see out the window, nor can you easily access the aisle.
