7(b) Consider the following facts:
1. If the maid stole the jewellery, then the butler wasn't guilty.
2. Either the maid stole the jewellery or she milked the cows.
3. If the maid milked the cows, then the butler got his cream.
4. Therefore, if the butler was guilty, then he got his cream.
Prove that the conclusion (step 4) is valid using resolution.
