84 (if you make a mistake in typing 84, instead you type 8.4

Step-by-step explanation:

In finding the value in this probem.

You need to use the formula of nCr (Combination) which is nCr = n! / (n – r)! r!

(n is the different objects taken r at a time.)

n=9

r=6

Therefore,

nCr= 9! / (9-6)!6!

nCr= 362880 / (6) 720

nCr= 362880 / 4320

nCr= 84
