 (a) How many samples were represented? 55 samples (b) How manyhad exactly one antigen? 27 samples (c) How many had exactly two

antigens? 11 samples (d) How many had O-positive blood? 7 samples (e)How many had AB-positive blood? 5 samples (f) How many had B-negative

(a) How many samples were represented? 55 samples (b) How many had exactly one antigen? 27 samples (c) How many had exactly two antigens? 11 samples (d) How many had O-positive blood? 7 samples (e) How many had AB-positive blood? 5 samples (f) How many had B-negative blood? 14 samples (g) How many had O-negative blood? 12 samples (h) How many had A-positive blood? samplesHuman blood can contain the A antigen, the B antigen, both the A and B antigens, or neither antigen. It may or may not also contain the Rh antigen. # of Samples Antigen in Blood Blood is called type A-positive if the individual has the A and Rh but not the B antigen. A person having only the A and B antigens is said to have 17 A type AB-negative blood. A person having only the Rh antigen has type O-positive blood. Other blood types are defined in a similar manner. In a 7 certain hospital, the data, shown to the right, was recorded. Use a Venn diagram to answer parts (a) through (h) about the blood samples. For A and B parts (d) through (h), the presence or absence of antigens determines blood type. 28 B 12 B and Rh 22 Rh 13 None (a) How many samples were represented? 8 A and Rh A, B, and Rh samples
