Franklin has three coins, two fair coins (head on one side and tail on the other side) and one two-headed coin. 1) He randomly picks one, flips it and gets a head. What is the probability that the coin is a fair one? 2) He randomly picks one, flips it twice. Compute the probability that he gets two tails. 3) He randomly picks one and flips it twice. Suppose B stands for the event that the first result is head, and...
