2.2. This problem is based on problems 4.8 and 5.17 in Berry (1996). Suppose the following statements are true for Minneapolis on January 15:

1. The probability that it snows both today and tomorrow is 0.2.

2. The probability that it snows today but not tomorrow is 0.1.

3. The probability that it snows tomorrow but not today is 0.1.

4. The probability that it snows neither today nor tomorrow is 0.6.

Find the probability that:

1. It will snow today.

2. It will snow either today or tomorrow or both.

3. It will snow tomorrow. 4.

It will snow tomorrow, given that it has snowed today.
