There are four blood types, and not all are equally likely to be in blood banks. In a certain blood bank, 49% of donations are Type O blood, 27% of donations are Type A blood, 20% of donations are Type B blood, and 4% of donations are Type AB blood. A person with Type B blood can safely receive blood transfusions of Type O and Type B blood. What is the probability that the 4th donation selected at random can be safely used in a blood transfusion on someone with Type B blood?
