What is the probability of both coins landing on heads?

Question

UpStudy AI · Accepted Answer

To find the probability of both coins landing on heads, we can follow these steps:

1. **Identify the total outcomes**: When flipping two coins, each coin has 2 possible outcomes: heads (H) or tails (T). Therefore, the total number of outcomes when flipping two coins is:
   $$
   2 \times 2 = 4
   $$
   The possible outcomes are: (H, H), (H, T), (T, H), (T, T).

2. **Identify the favorable outcomes**: The only favorable outcome for both coins landing on heads is (H, H). Thus, there is 1 favorable outcome.

3. **Calculate the probability**: The probability $$ P $$ of an event is given by the formula:
   $$
   P = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}
   $$
   Substituting the values we found:
   $$
   P = \frac{1}{4}
   $$

Therefore, the probability of both coins landing on heads is $$ \frac{1}{4} $$ or 0.25.
The probability of both coins landing on heads is 1 out of 4, or 0.25.
