6.4 Let Yl be the number of successes in n = 10 independent trials where each trial results in a success or failure, and T, the probability of success, remains constant over all trials. Suppose the 4 possible values of 7r are .20, .40, .60, and .80. We don’t wish to favor any value over the others so we make them equally likely. We observe Yl = 7. Find the posterior distribution by filling in the simplified table.
