If you flip a coin 3 times, what is the probability of flipping heads 3 times?

Each flip is independent of each other.

For single flip, the probability of getting a head would be 1/2 because there are two outcomes in total (head and tail), and there are one desired outcome (head).

Now for three flips, we need 3 heads. So we need head for first flip, second, and third too, so that would be (1/2) (1/2) (1/2) = 1/8

Final answer: 1/8
