A coin is tossed successively three times. The probability of getting exactly one heads or 2 heads is

Options

A. `(1)/(4)`
B. `(1)/(2)`
C. `(3)/(4)`
D. `(3)/(2)`

Answer

To solve the problem of finding the probability of getting exactly one head or exactly two heads when a coin is tossed three times, we can follow these steps:

### Step 1: Identify the total number of outcomes
When a coin is tossed three times, each toss has 2 possible outcomes: heads (H) or tails (T). Therefore, the total number of outcomes when tossing the coin three times is calculated as:
\[ \text{Total outcomes} = 2^3 = 8 \]
