**Problem 7.** Consider the following table formed by a population of 70.

\[
\begin{array}{c|c|c}
 & A & B \\
\hline
X & 22 & 17 \\
Y & 18 & 13 \\
\end{array}
\]

**Part A.** Find \( P(A) \), \( P(B) \), \( P(X) \), \( P(Y) \).

**Part B.** Find the probability of \( X \cap B \) and \( X \cup B \).

**Part C.** Find the conditional probability of \( P(X|A) \) and \( P(B|Y) \).

### Explanation of the Table:

The table represents a population divided into different categories. The rows are labeled as \( X \) and \( Y \), and the columns are labeled as \( A \) and \( B \). The numbers in the table represent the count of individuals in each category.

- The number 22 corresponds to category \( X \) and column \( A \).
- The number 17 corresponds to category \( X \) and column \( B \).
- The number 18 corresponds to category \( Y \) and column \( A \).
- The number 13 corresponds to category \( Y \) and column \( B \).

The total population is given as 70.
