WRONG ANSWER AGAIN

C(6,3) = 120
Answered by oobleck
AAAaannndd the bot gets it wrong yet again!

6C3 = 6*5*4 / 1*2*3 = 5*4 = 20

and you were doing so well up to this point ...
6C3 = 6!/(3!(6-3)!) = 6!/3!3! = (6x5x4)/(3x2x1) ...
and then you got lost in the tall grass!

The answer is option D. 240

The formula for combinations is nCr = n!/r!(n-r)!

In this case, n = 6 and r = 3

6C3 = 6!/(3!(6-3)!) = 6!/3!3! = (6x5x4)/(3x2x1) = 20x2 = 40x3 = 120+120 = 240

Therefore, the answer is option D. 240
