Math Problem Statement
Solution
The image contains a probability table for a pair of random variables and , along with the question to find , the conditional probability.
To solve for , we use the following formula for conditional probability:
Step-by-step approach:
-
Find : From the table, the probability of and is 10/100 (or 0.10).
-
Find : We sum all probabilities where . From the table:
- For , the probabilities for are:
-
Apply the formula:
So, the conditional probability is approximately 0.36 (rounded to two decimal places).
