Question 15 • **MFISD GEOMETRY B 22-23 CR

Brent’s after-school game club has 12 members from which a six-member team is created. Miguel’s after-school sports club has 10 members from which a six-member team is created.Which student’s club has more possible combinations for his six-member team?

Answer
A
Brent’s club has more possible team combinations because he has fewer members on each team than Miguel’s does.
B
Brent’s club has more possible team combinations because there are more members to choose from.
C
Miguel’s club has more possible team combinations because there are fewer members in his club.
D
Miguel’s club has more possible team combinations because he has more members on each team than Brent does.

Explanation

A team is chosen without regard to order, so use combinations. Brent’s club has C(12, 6) = 924 possible teams, while Miguel’s club has C(10, 6) = 210. Since 924 is greater than 210, Brent’s club has more possible team combinations because there are more members to choose from.
