Amath teacher assigns 3 projects. she gives the students 5 project options to choose frorm how many different groups of projects can the students choose from?

10

Step-by-step explanation:

This is a combination problem since the order does not matter.

nCr = n! / r! * (n - r)!  

where n is the number of things  (5 projects)

and r is the number of things chosen

! means factorial which is multiply that number and all the numbers below it

5C3 = 5!                     5!            5*4*3*2*1

                 =   =  

          3! ((5-3)!         3!  2!         3*2*1 (2*1)

Canceling like terms leaves

5C3 = 5*4/2 = 20/2 = 10

if this is really you s much. i only have 3 points left and i have 2 questions to ask

oof
