Kiwifruit as an iron supplement. An article published in BMC Public Health (Vol. 10, 2010) studied the effectiveness of gold kiwifruit as an iron supplement in women with an iron deficiency. Fifty women were assigned to receive an ironfortified breakfast cereal with a banana, and 50 women were assigned to receive an iron-fortified breakfast cereal with gold kiwifruit. At the conclusion of the 16-week study, the medical researchers selected two women from each group and performed a full physical examination on each. How many possible ways could the selections be made?
