Answer
0.00045, very unlikely.
Work Step by Step
Events are dependent, if the outcome of one effects the outcome of the other. Here the events are dependent, because sampling was done without replacement. $P(A \cap B \cap C)=P(A)\cdot P(B|A)\cdot P(C|(A \cap B))$. Hence $P(A \cap B \cap C)=\frac{24}{300}\cdot\frac{23}{299}\cdot\frac{22}{298}=0.00045.$ Hence it is very unlikely.
