You flip a coin twice. What is the probability of getting heads and then getting heads? Write your answer as a percentage.

There are 4 possible outcomes when flipping a coin twice: heads-heads, heads-tails, tails-heads, and tails-tails.

Out of these 4 outcomes, only 1 of them is heads-heads.

Therefore, the probability of getting heads and then getting heads is 1 out of 4, or 1/4.

To convert this to a percentage, we multiply by 100:

1/4 * 100 = 25%

So, the probability of getting heads and then getting heads is 25%.
