The potential outcomes of an experiment consist of the following triples: (a, a, a) (b, b, b) (c, c, c) (a, b, c) (b, c, a) (c, b, a) (a, c, b) (b, a, c) (c, a, b) Assume that every outcome in the sample space is equally likely. Define the following events: A1 = "letter 'a' is in the triple's first position," A2 = "letter 'a' is in the triple's second position," and A3 = "letter 'a' is in the triple's third position." For example, (a, b, c) is a member of A1, (b, a, c) is a member of A2, and (c, b, a) is a member of A3. What is P(A1 | A2)? O 1 1/3 O 2/3 1/9
