Evaluate c (9, 3). 504 84 60,480 5,040

Using the combination formula, it is found that C(9,3) = 84.

is the number of different combinations of x objects from a set of n elements, given by:

Hence, applying the above formula for n = 9, x = 3:

Thus, it is found that C(9,3) = 84.

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
