The coins were tossed and probability was used to determine the process of decay. The coins were put in a flat box with a cover and the box was shaken for a couple of seconds. After shaking, the coins were poured out onto a flat surface. The coins with their heads up were decayed. The coins with tails up were not decayed.
Ten random tosses were made after shaking the box and the count of decayed coins was made after each toss. The decayed coins were then removed and the other coins returned into the box for more shake and spread on the table.
According to the first hypothesis, the results show that the nine tosses from the box lead to decay of all coins. The line graph of experiment one shows that there is a gradual but approximately consistent decay of the 195 coins used.
The second hypothesis according to the table is also averagely true. The results show that in four out of nine tosses, more than half of the coins decay. The cumulative frequency shows that all the 195 coins decay eventually.
The coins were replaced with 16 new coins after every trial. The different sets of coins were put in the box and shaken then tossed on a table. The results were taken to determine the number of coins that decayed on the first throw.
The coins should not be put in a box because collecting many boxes is tedious. They should be tossed only. One person should collect decayed coins, another tosses only. To avoid tampering with the decay substance. Time should also be calculated within tosses to ensure ...Download file to see next pagesRead More
