**Probability and Statistics - Example Problem**

**Question:**
If the probability that it will snow tomorrow is 0.15, what is the probability that it will not snow tomorrow?

**Options:**
1. 0.15
2. 0.70
3. 0.85
4. 1
5. None of the above are correct. 

**Explanation:**
In probability theory, the probability of an event occurring plus the probability of it not occurring must equal 1. Given that the probability it will snow tomorrow is 0.15, we can calculate the probability that it will not snow as follows:

\[ P(\text{Not Snow}) = 1 - P(\text{Snow}) = 1 - 0.15 = 0.85 \]

Thus, the correct answer is 0.85.
