Question

You flip a coin twice. What is the probability it lands heads-up both times?

Answer 1

Answer: 1/4

Step-by-step explanation: 1/2 chance it shows heads if you do it once so: 1/2 times 1/2

Answer 2

Answer:

$\frac{1}{4}$

Step-by-step explanation:

Each time you a flip a coin, there is a $\frac{1}{2}$ chance it lands on heads. Therefore, after flipping a coin twice, the probability that it lands on heads both times is:

$\frac{1}{2}\cdot \frac{1}{2}=\boxed{\frac{1}{4}}$
