Step-by-step explanation:
1. For every coin, two options are possible. The formula for calculting all possibilities is p(power t). where p is possibilities per time and t is times.
Therefore, there are 2¹⁰ which is 1024 combinations.
2. The formula for calculating probability is w/t. where w is the ways to achieve the desired outcome, and t is the total outcomes possible.
Therefore, there is a 1/1024 chance of flipping ten tails.
