(a) What is the change in entropy (in J/K) if you start with 100 coins in the 60 heads and 40 tails macrostate, toss them, and get 45 heads and 55 tails?

(b) What if you get 25 heads and 75 tails (in J/K)?

(c) How much more likely is 45 heads and 55 tails than 25 heads and 75 tails (times more likely)?

Problem 5: You play the following game and you start by investing $100. Two coins are flipped. Head: you get starting balance +30% Tail: you get starting balance -20% Potential outcomes: 1-head+head: gain 60% 2-head + tail: gain 10% 3-tail +head: gain 10%. 4-Tail+tail: loose 40%. *There is a 25% chance of making 60%, 50% chance of making 10% and 25% of losing 40%. What are the variance and the standard deviation of this coin game?

To test the hypothesis that a coin is fair, you toss it 100 times. Your decision rules allow you to accept the hypothesis only if you get between 40 and 60 tails in 100 tosses. What is the probability of committing Type II error when the actual probability of tails is 0.7?

If I tell you that I have a coin, but it is a special coin. In that, I mean that it is not a 50/50 coin. However, I don't know how likely it is for it to land on heads (or tails). So we decide to flip it 10 times and we get 40% heads (which is 0.40 as a proportion). Are you willing to say that it is a 40/60 coin? Why or why not? after we flipped it...
