Can anyone help me in figuring out why the answer to the following question is "greater than 2"?

Assuming that P50 = 26 torrs, under conditions where pO2 = 30 torrs, the average number of O2 molecules bound per hemoglobin molecule is closest to

a. 0.5.
b. less than 1.
c. almost 2.
d. greater than 2.
e. greater than 3.

Each hemoglobin carries 4 oxygen molecules, so P50 (half saturation) would be 2 molecules. Since the pO2 is over the P50 pressure, the average number of O2 molecules bound to hemoglobin would come out to just over 2.
