To find the probability of Outcome Y given that Outcome 2 occurs, you need the total number of occurrences associated with Outcome 2. Looking at the table, the total occurrences for Outcome 2 are:
The total for Outcome 2 is \(9 + 4 = 13\).
Therefore, the denominator of your fraction when using the formula \(P(A|B) = \frac{n(A \text{ and } B)}{n(B)}\) will be:
13
