2. The odds in favor of an event are the number of successes divided by the number of failures. The probability of this event occurring is the number of successes divided by the sum of the number of successes and the number of failures. The number of successes is five and the number of failures is four.Find the probability of failure.
3. A firm produces three qualities of bed linens -- good, better, best. Production is scheduled to result in 50% good, 35% better, and 15% best. A quality control person checks the finished product and classified them as acceptable or imperfect. The percentages acceptable are good, 92%; better, 88%; best, 82%. Find the posterior probability that a sheet, which is "acceptable", will be acceptable.
