Decision Table - Jacket Weather

Determine whether you need to wear a light jacket, heavy jacket, or no jacket at all when you leave the house. You need a heavy jacket if the temperature is below 50 degrees. You can make do with a light jacket if the temperature is between 50 and 70. At 70 and above you only need a light jacket if there is precipitation.

There will be 6 rules. The first condition (Is there precipitation?) has two possible outcomes, yes or no. The second condition (temperature) has three possible outcomes. Two times three is 6.
