Question

2 members of a gymnastics team are randomly chosen to compete in an invitational. If there are 9 members on the team, how many ways could be chosen?

Answer 1

There are 36 ways to choose 2 members from a team of 9.

Step-by-step explanation:

To determine the number of ways 2 members can be chosen from a team of 9, we can use the combination formula. The formula for combinations is nCr = n! / (r!(n-r)!), where n is the total number of items to choose from and r is the number of items to be chosen.

In this case, we have 9 members on the team and we want to choose 2 members. Therefore, the number of ways 2 members can be chosen from a team of 9 is given by,

9C2 = 9! / (2!(9-2)!)

= 9! / (2!7!)

= (9*8) / (2*1)

= 36 ways.
