This process is called transmutation. An element keeps changing as the nucleus loses energy and mass.
Coins are metallic. They also are elements that contain mass. They are fit because they have heads and tails. Radioactivity can be determined when the coins land on a different side to mean that they have lost energy and mass. It is a probabilistic method, but it works well to establish the hypothesis involved.
Probability is used in these experiments determine half-life and the process of decay. It is a game. It uses random actions to prove certain trends. Probability is also used here to track progress of decay of the coins. It eliminates decayed coins against non-decayed.
Two random experiments were conducted to determine radioactive decay of random coins. The purpose was to come up with a statistical explanation for their radioactivity and to establish the procedure. The coins were tossed and probability was used to determine the process of decay. The coins were tossed and each coin that landed on its head was decayed. Each coin that was on its tails was not decayed. This was the mode of separation for the decay process.
The second hypothesis is also a little faulty. It is almost 3. An average of 2.97 is recorder in the table to mean that the throws after the first are mostly two or three to create two or less coins
