Suppose we have two weighted coins, one of which comes up heads with probability 0.2, and the other of which comes up heads with probability 0.9. Unfortunately, the coins are otherwise identical, and we have lost track of which is which. Suppose we flip a randomly chosen coin 14 times and let be the random variable giving the number of heads seen. If in the first 4 flips we see 3 heads, what is the conditional expected number of heads in the 14 flips?

A big bowl contains 3 red chips and 6 white chips. A chip is drawn at random. If it is red, that chip along with an additional red chip will be put back in the bowl. If it is white, the chip is simply returned to the bowl. Next a second chip is drawn. If the 2nd chip is white, what is the probability that the first is red? The answer as 9/29. But I don't know the work.

From a bag of mixed flower seeds, 12 flowers are planted. Each flower, independently, has a 1/7 chance of being yellow, a 2/7 chance of being white, and a 4/7 chance of being red. What is the probability that when the flowers grow, there are 4 yellow, 4 white, and 4 red flowers?
There are three containers, A, B and C. Each container contains 25 balls, which are either red or blue. Container A has 15 red balls, container B has 16 red balls, and container C has 12 red balls. In a random experiment, one first randomly chooses a container, and then a ball is drawn from the chosen container. The probability of choosing container B in step 1 is 2/5 . The experiment is designed so that the events “the ball drawn is red” and “the ball drawn comes from container A” are independent. Suppose that the ball drawn is red. What is the probability that it came from container C?
Assume that the weighted coin yields a heads with probability 0.75. You select one of the two coins at random, and flip it 3 times, noting heads or tails with each flip. What is the probability that the weighted coin was selected, given that all 3 flips turned up heads?
