Find the number of possible outcomes of tossing a coin four times.

Explanation

To find the number of possible outcomes of tossing a coin four times, we can follow these steps:

### Step 1: Understand the Problem
When a coin is tossed, there are two possible outcomes: Heads (H) or Tails (T).

**Hint:** Remember that each toss is independent of the others.

### Step 2: Determine the Number of Tosses
In this problem, we are tossing the coin 4 times.

**Hint:** Identify how many times the experiment (coin toss) is being conducted.

### Step 3: Calculate the Total Outcomes
The formula to find the total number of outcomes when a coin is tossed \( n \) times is given by:
\[ \text{Total Outcomes} = 2^n \]
where \( n \) is the number of tosses.

**Hint:** Think about how each toss doubles the number of outcomes.

### Step 4: Substitute the Value of \( n \)
Here, \( n = 4 \). So we substitute this value into the formula:
\[ \text{Total Outcomes} = 2^4 \]

**Hint:** Perform the exponentiation step carefully.

### Step 5: Calculate \( 2^4 \)
Calculating \( 2^4 \):
\[ 2^4 = 16 \]

**Hint:** Remember that \( 2^4 \) means multiplying 2 by itself 4 times.

### Conclusion
Thus, the total number of possible outcomes when tossing a coin four times is **16**.

**Final Answer:** 16
