Suppose that a box contains five coins and that for each coin there is a different probability
Question:
a. Suppose that one coin is selected at random from the box and when it is tossed once, a head is obtained. What is the posterior probability that the ith coin was selected (i = 1, . . . , 5)?
b. If the same coin were tossed again, what would be the probability of obtaining another head?
c. If a tail had been obtained on the first toss of the selected coin and the same coin were tossed again, what would be the probability of obtaining a head on the second toss?
