I tried to solve this for over two hours without any successful results.
If you could please provide the solution and explain how you arrived at it, it would be very much appreciated. I am perplexed at this point.
An experiment with coins is performed. The experimenter starts with 4 coins. Each time she tosses the coins into the air, after they land, she counts the number of heads that appear and adds that amount (the number of heads) of coins to what she previously had. (i.e she tosses 4 coins, 2 out of 4 are heads, 4+2=she now has six coins.)
The experimenter repeats this process and claims that one could make a rough prediction about how the coins will increase (given any amount of tosses) based on the formula for compound interest: A=P(1+ i)n
In this case, P represents the amount of coins she started with.
i = 0.5 since the 50% probability of the coins landing on heads.
n= the number of tosses
If her her hypothesis is correct, create a formula that predicts the total number of coins if an unfair coin is used (a weighted coin included in her starting amount of 4) that only comes up heads 1 out of every 4 times.
Thanks in advance.
