Answer

Explanation:

Step1: List all possible outcomes

When flipping a penny and a dime, the possible outcomes are (penny - head, dime - head), (penny - head, dime - tail), (penny - tail, dime - head), (penny - tail, dime - tail). So there are a total of 4 possible outcomes.

Step2: Identify the favorable outcome

The favorable outcome for getting two heads is only 1 case: (penny - head, dime - head).

Step3: Calculate the probability

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. Here, the number of favorable outcomes for getting two heads is 1 and the total number of outcomes is 4. So $P(2\text{ heads})=\frac{1}{4}$.

Answer:

D. $P(2\text{ heads})=\frac{1}{4}$
