hello Coin 1 is biased, with P(H)=0.2; Coin 2 is also biased, with P(H)=0.6; Coin 3 is fair. One of these coins is randomly selected, and then flipped. Calculate: a) P(result of the flip is T). b) P(coin selected was the fair one, if the result of the flip is H). c) Assuming now that one of the coins is randomly selected and then flipped 2 times, calculate P(coin selected was the fair one, if result of the flips is...
