The chance of flipping heads or tails is 50%.
We have to flip heads or tails 3 times.
To make this easier, I will convert 50% to 1/2 for the time being.
Since the chance of getting heads or tails is 1/2 and there are 3 flips, multiply 1/2 to the power of 3, which is 1/8
1/8 is the probability of getting this outcome.
