The correct Answer is:
To solve the problem of finding the probability of obtaining two heads when two coins are tossed, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Experiment**: We are tossing two coins. Each coin can land on either heads (H) or tails (T). 2. **Determine the Total Outcomes**: When two coins are tossed, the possible outcomes can be listed as: - HH (both coins show heads) - HT (first coin shows heads, second coin shows tails) - TH (first coin shows tails, second coin shows heads) - TT (both coins show tails) Therefore, the total number of outcomes is 4. 3. **Identify the Favorable Outcomes**: We are interested in the event where both coins show heads. From our list of outcomes, we see that there is only 1 favorable outcome: - HH Thus, the number of favorable outcomes is 1. 4. **Calculate the Probability**: The probability of an event is given by the formula: \[ \text{Probability} = \frac{\text{Number of Favorable Outcomes}}{\text{Total Number of Outcomes}} \] Substituting the values we found: \[ \text{Probability of getting 2 heads} = \frac{1}{4} \] 5. **Conclusion**: The probability of obtaining two heads when two coins are tossed is \( \frac{1}{4} \).
