To find the probability of Outcome Y given that Outcome 2 occurs, we need to understand the notation used in the formula P(A|B) = n(A and B) / n(B).
In this case:
- Event A is Outcome Y.
- Event B is Outcome 2.
To compute P(Y|Outcome 2), we need:
1. n(A and B): the number of occurrences where both Outcome Y and Outcome 2 happen. From the table, this value is 4 (the intersection of Outcome Y and Outcome 2).
2. n(B): the total number of outcomes when Outcome 2 occurs. We need to sum the counts of both Outcome X and Outcome Y for Outcome 2 from the table, which is 9 (from Outcome X) + 4 (from Outcome Y) = 13.
So, the number you would use in the denominator n(B) when calculating P(Y|Outcome 2) is **13**.
The correct response is:
13
