A coin is tossed twice. Find the probability of getting:
exactly one head

Answer

To find the probability of getting exactly one head when a coin is tossed twice, we can follow these steps:

### Step 1: Determine the total number of outcomes
When a coin is tossed, there are 2 possible outcomes: Heads (H) or Tails (T). When the coin is tossed twice, the total number of outcomes can be calculated using the formula for the number of outcomes of independent events:

\[ \text{Total Outcomes} = 2 \times 2 = 4 \]

The possible outcomes are:
1. HH (Head, Head)
2. HT (Head, Tail)
3. TH (Tail, Head)
4. TT (Tail, Tail)
