In a group of 1000 people, only 5% have Type AB blood. a) On average, how many donors must be checked to find someone with Type AB blood? b) What's the probability that there is a Type AB donor among the first 5 people checked? c) What's the probability that the first Type AB donor will be found among the first 6 people? d) What's the probability that there won't be a Type AB donor before the 8th person? a) On average, 20. donors must be checked to find someone with Type AB blood. b) The probability that there is a Type AB donor among the first 5 people checked is 0.226 (Round to three decimal places as needed.) c) The probability that the first Type AB donor will be found among the first 6 people is 0.265 (Round to three decimal places as needed.)
