Answer:
Option A.
Step-by-step explanation:
Hector has 15 shirts in his drawer that are all the same size and shape. 6 shirts are white, 4 shirts are blue, 3 shirts are red and 2 shirts are green.
It is given that randomly selects two shirts without replacement.
In without replacement the outcome is dependent on preceding outcome and in with replacement the outcome is independent of preceding outcome.
The outcome of the second shirt is dependent on the outcome of the first shirt, because not replacing the first shirt affects the outcome of the second shirt.
Therefore, the correct option is A.
