If a coin is tossed n times, then find the probability that the head appears odd number of times.

Explanation

To find the probability that a head appears an odd number of times when a coin is tossed \( n \) times, we can follow these steps:

### Step 1: Determine the Total Outcomes
When a coin is tossed \( n \) times, each toss has 2 possible outcomes: heads (H) or tails (T). Therefore, the total number of outcomes when tossing the coin \( n \) times is given by:
\[ \text{Total outcomes} = 2^n \]
