A box contains N coins, m of which are fair and the rest are biased. The probability of getting a head when a fair coin is tossed is 1/2, while it is 2/3 when a biased coin is tossed. A coin is drawn from the box at random and is tossed twice. The first time it shows head and the second time it shows tail. What is the probability that the coin drawn is fair?
Suppose that there is a white urn containing two white balls and three red balls and there is a red urn containing two white balls and four red balls. An experiment consists of selecting at random a ball from the white urn and then (without replacing the first ball) selecting at random a ball from the urn having the color of the first ball. Find the probability that the second ball is red.
Suppose that there is a white urn containing three white balls and one red ball and there is a red urn containing two white balls and four red balls.

Find the probability that the second ball is red.
Three six-sided dice are in an urn: one fair die and two trick dice. One of the trick dice always lands on either 2, 4, or 6, with equal probability, while the other trick die always lands on 1, 3, or 5, with equal probability. 9. You draw one die at random and roll it. What is the probability that you drew the fair die, given that the roll is at least 4?
