Question 348343: Urn A has 6 white and 4 red balls. Urn B has 16 white and 13 red balls. We flip a fair coin. If the oucome is heads, then a ball from urn A is selected, whereas if the oucome is tails, then a ball from urn B is selected. Suppose that a red ball is selected. What is the probability that the coin landed heads?
Please show your work. Thank you so much! :]
