Find the truth values of the following compound statements :
`(a) (pvv~r) ^^(qvv~r) " " (b) ~ (pvv~q) ^^(~ pvvr)`

Explanation

To find the truth values of the given compound statements, we will create truth tables for each statement.

### Statement (a): \((p \lor \neg r) \land (q \lor \neg r)\)

1. **Identify Variables**: The variables involved are \(p\), \(q\), and \(r\).
2. **Construct the Truth Table**: We will list all possible combinations of truth values for \(p\), \(q\), and \(r\).

| \(p\) | \(q\) | \(r\) | \(\neg r\) | \(p \lor \neg r\) | \(q \lor \neg r\) | \((p \lor \neg r) \land (q \lor \neg r)\) |
