Answer:
84
Step-by-step explanation:
Combinations
nCr
n (objects) = 9
r (sample) = 3
9C3
n! / r! (n – r)!
9! / 3! (9 – 3)!=
9! / (3! * 6!)=
9*8*7*6!/ (3! * 6!)=
6! cancels out
9*8*7/3*2*1=
3*4*7=
12*7=
84
Factor out common numbers or variables when you can.
To make this the most simplified factor, factor out n², as it is the least factor both have.
n³/n² = n
-2n²/n² = -2
n - 2 is your new answer
hope this helps
