ANSWER THE MISSING NUMBERS IN THE BOX A relief organization must track its supply and demand for various blood types. It estimates that about 44% of the population in a country has Type 0 blood, 40% Type A, 10% Type B, and the rest Type AB. Among four potential donors, what is the probability that a) All are Type O? b) None have Type AB blood? c) Not all are Type A? d) At least one person is Type B? a) The probability that all four donors are Type O is (Round to three decimal places as needed.) b) The probability that none of the donors have Type AB blood is (Round to three decimal places as needed.) c) The probability that not all of the donors are Type A is (Round to three decimal places as needed.) cl) The probability that at least one donor is Type B is (Round to three decimal places as needed.) ANSWER THE MISSING NUMBERS IN THE BOX In one region, 75% of people speak English only when they are at home, 12% speak only French, 10% speak only another language, and the remainder speak more than one language. Suppose that you are conducting a poll by calling people in this region at random. For your first three calls, find the following probabilities. a) What is the probability that you talk to only people that speak only English at home? b) What is the probability that you talk to no people that speak only French at home? c) What is the probability that you talk to at least one person who speaks only a different language at home? a) The probability is (Type an integer or a decimal. Do not round.) b) The probability is (Type an integer or a decimal. Do not round.) c) The probability is (Type an integer or a decimal. Do not round.)
