When I was an undergraduate, I helped my father conduct some Child Psychology research about parental influence on gender bias. In this study we interviewed 158 kindergarteners. Our initial question was "What is your favorite color?" where we studied the distribution of "Pink" and "Blue" responses. To our surprise, 38 of the students interviewed responded "Turquoise". Use this information to select the response which correctly answers the question. Being curious, we decided to further interview the children who responded "Turquoise". While he took a lunch break, he told me to select 5 such children to form a group for interviews. How many different possible groups could I have formed? O 769754986 O 5.297 x 1036 O 501942 O 1109750
