Describe 2 events where the probability is 0%
1. A coin landing perfectly on its edge - The probability of a coin landing on its edge is theoretically possible, but in practice, it is highly unlikely due to factors such as the shape and thickness of the coin, the surface it lands on, and various other variables. Therefore, the probability of a coin landing perfectly on its edge is effectively 0%.
2. A person jumping off a building without any safety measures and surviving unharmed - While it is technically possible for someone to survive a fall from a great height without injury, the probability of this occurring is extremely low. The force of impact from such a fall would likely result in serious injury or death. Therefore, the probability of someone jumping off a building without any safety measures and surviving unharmed is practically 0%.
