Answer

Unlikely

Work Step by Step

We know that $probability=\frac{number \ of \ good \ outcomes}{number\ of\ all\ outcomes}$. Therefore $probability=\frac{19}{19+441+235+103+66+75}=\frac{19}{939}≈0. 2023<0.05$. The outcome is unlikely if it's probability is less than 0.05. Therefore it is unlikely.
