Each of the teams in a mixed volleyball league consists of 5 men and 5 women. There are 9 men and 10 women, including Julia, who are trying out for a team. How many possible teams would include Julia?

The total number of teams that would include Julia is 15,876.
For the men's team we need to select 5 out of 9 options, then the total number of different options is:
[tex]C(9, 5) = \frac{9!}{(9 - 5)!*5!} = \frac{9*8*7*6}{4*3*2*1} = 126[/tex]
For the women's case, there are 10, but Julia needs to be on the team, so we only need to select another 4 women from the other remaining 9.
The number of combinations is:
[tex]C(9, 4) = \frac{9!}{(9 - 4)!*4!} = 126[/tex]
The total number of combinations is the product of the two we found:
C = 126*126 = 15,876
We conclude that the correct option is the first one.
