Let's solve each of these questions one by one.

1. **What is the probability of 3 heads?**

   For 3 heads, we need to get a head on each flip. Each flip is independent, so:
   
   \[
   P(\text{3 heads}) = \left(\frac{1}{2}\right)^3 = \frac{1}{8}
   \]

2. **What is the probability of 2 heads and 1 tail in any order?**

   There are three ways to get 2 heads and 1 tail: HHT, HTH, and THH. Each sequence has a probability of \(\frac{1}{8}\), so:
   
   \[
   P(\text{2 heads and 1 tail}) = 3 \times \frac{1}{8} = \frac{3}{8}
   \]

3. **What is the probability of 1 head and 2 tails in any order?**

   Similarly, there are three ways to get 1 head and 2 tails: HTT, THT, and TTH. Each sequence also has a probability of \(\frac{1}{8}\), so:
   
   \[
   P(\text{1 head and 2 tails}) = 3 \times \frac{1}{8} = \frac{3}{8}
   \]

4. **What is the probability of 3 tails?**

   For 3 tails, we need a tail on each flip. Thus:
   
   \[
   P(\text{3 tails}) = \left(\frac{1}{2}\right)^3 = \frac{1}{8}
   \]

### Summary of Answers:

1. Probability of 3 heads: **1/8**
2. Probability of 2 heads and 1 tail: **3/8**
3. Probability of 1 head and 2 tails: **3/8**
4. Probability of 3 tails: **1/8**
