Human beings have 4 types of basic blood type: AB, A, B and O. In the US, about 43% of people are O type, 43% of people are A type, 10% of people are B type and 4% of people are AB type'. Now you are a doctor and have two patients waiting for blood transfusion. One of them has blood type O and can only accept blood type 0 transfusion; the other has blood type A and can receive either type O or A transfusion. Assume every donor's contribution can only support one patient (that is, one donor cannot donate blood to both patients). If you choose 5 donors randomly from the population, what's the probability that both of the patients are able to get blood transfusion? Round to four decimal places.
