Tk, but do not get less than 50. Write down the number of pennies you obtained, N. 50 N = We will consider that tails represents a nucleus that has not undergone decay yet (so it is still unstable), and heads a nucleus that has undergone decay. When a nucleus has undergone radioactive decay, it becomes stable and does not decay anymore. 1. If we throw a penny in the air, what is the chance you will get heads or tails? Based on your answer, what is the chance you get a nucleus that has undergone radioactive decay? 144baSed Lor which Side ofthe corn was throwninto the air 2. So, if we throw the N pennies in the air, how many will have undergone "decay" in one throw? 5012-15

Answer 1

1.) Penny has two sides head and tail and in one throw either head or tail will come up. so there are 1/2 or 0.5 or 50 % chances to get head or tail. Based on this answer, there are 1/2 or 0.5 or 50 % chances to get undergone radioactive nuclei. 2) If we throw N pennied up in the air, we will have N*1/2 = N/2 undergone decoay in one throw.
