there are two coins, one fair and one biased. the biased coin comes up heads with a probability 0.8 and tails with a probability 0.2. one of the coins is selected at random and flipped ten times. the results of the coin flips are mutually independent. the result of the 10 flips is h, t, t, h, h, t, h, h, t, h. what is the probability that the coin flipped was the biased coin? (round to the nearest tenth.)
