Sarah has 5 friends who are available to go with her to the movies, but she only has

3 extra tickets. How many different choices does Sarah have for which 3 friends to invite.

10 different choices

Step-by-step explanation:

This is a combination problem: we need to make groups of 3 people among 5 people, and the order of the people inside a group doesn't matter (does not make a different group).

If the total number of people is 5 and we need groups of 3, this is a combination of 5 choose 3:

C(5,3) = 5!/(3!*2!) = 5*4/2 = 10

Sarah has 10 different choices

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.
