Suppose that you have a bag with 3 coins. One of them is a fair coin, but the others are biased trick coins. When flipped, the three coins come up heads with probability 21,31, and 41, respectively. Consider the experiment where you pick one coin at random and flip it three times. Let Hi be the event that the coin comes up heads on flip i. What is the probability of the outcome H1H2H3 ? With small modification in your code, find out the probability of the outcome H1H2H3. Use simulation to find out the probability
