50/50
you see, the coin only has 2 sides
Also, you're flipping it twice
therefore, the probability is matched up and you have a 50/50 chance of getting heads at least 1 of those 2 times
(Hope it helped ^_^)
Answer:
Weathering and erosion are natural geological processes that act like rocks and soil on the earth's surface, moving and reshaping the earth. Weathering is the breaking down of rocks into smaller pieces by changing the size and structure of the rocks. The forces of nature are largely responsible for this process. Erosion involves processes such as wind, water flow, and ice movement, which results in change from one place to another.
A field biologist who studies the behavior of birds in a rainforest most likely collects data through observation.
Rainforests are the areas with rich diversity of plants as well as animal species. The trees of rainforests are so long, broad and thick that they completely cover the canopy. They are also recognized by highest rainfalls. Rainforests are considered to be the oldest in the in the Earth's ecosystems.
Observation is the act of carefully watching any action or scenario in order to gain information. Observation can be turned into a formal activity when any data is collected through it for educational or experimental purposes.
