*A. consider tossing three coins, one after the other. How many different arrangements are possible? (answer 8 for 2^n) but the following I'm unsure about*

**B.** We will call each of the arrangments above a **microstate**. Arrange the microstates into groups according to the number of heads. We will call these groupings a **macrostate**.

For example:

HHH (3 heads)

HHT (2 heads)

**How many macrostates are possible for three coin tosses?**

**C.** **How many microstates correspond to the macrostate of two heads?**

**D. Suppose you were to toss three coins in a row. What is the probability that two coins land heads up?** (percentage as decimal)
