Question 38 (iii) (Choice B) People with blood type AB positive (AB+) are known as the universal recipient and with blood type O negative (O−) are known as universal donor. Find the probability of a selected person to be neither universal recipient nor universal donor. P(person is neither universal recipient nor universal donor) = 1 – P(person is universal recipient or universal donor) =1−(𝑃𝑒𝑜𝑝𝑙𝑒 𝑤ℎ𝑜 𝑎𝑟𝑒 𝑈𝑛𝑖𝑣𝑒𝑟𝑠𝑎𝑙 𝑟𝑒𝑐𝑒𝑖𝑝𝑖𝑒𝑛𝑡 𝑜𝑟 𝑑𝑜𝑛𝑜𝑟)/(𝑇𝑜𝑡𝑎𝑙 𝑝𝑒𝑜𝑝𝑙𝑒) =𝟏−(𝑷𝒆𝒐𝒑𝒍𝒆 𝒘𝒊𝒕𝒉 〖𝑨𝑩〗^+ + 𝑷𝒆𝒐𝒑𝒍𝒆 𝒘𝒊𝒕𝒉 𝑶^−)/𝟏𝟎𝟎 =1−(3 + 10)/100 =𝟏−𝟏𝟑/𝟏𝟎𝟎 =(100 − 13)/100 =𝟖𝟕/𝟏𝟎𝟎
