Step 1 :The problem is asking for the probability of selecting a green long-sleeved shirt. We know that one-sixth of the shirts are long-sleeved and one-third of the long-sleeved shirts are green.
Step 2 :We can calculate this probability by multiplying these two probabilities together.
Step 3 :Let's denote the probability of a shirt being long-sleeved as \(P(L) = \frac{1}{6}\) and the probability of a long-sleeved shirt being green as \(P(G|L) = \frac{1}{3}\).
Step 4 :The probability of selecting a green long-sleeved shirt is then given by \(P(G \cap L) = P(L) \times P(G|L)\).
Step 5 :Substituting the given values, we get \(P(G \cap L) = \frac{1}{6} \times \frac{1}{3} = \frac{1}{18}\).
Step 6 :Final Answer: The probability of selecting a green long-sleeved shirt from the closet is \(\boxed{\frac{1}{18}}\).
