Answer:
7 available
Explanation:
Since 3 colors are available r = 3
Total combination = 35
nCr = 35 ---1
nCr = n!/(n-r)!r!---2
We put equation 1 and 2 together
n-1)(n-2)(n-3)!/n-3)! = 35x 3!
We cancel out (n-3)!
(n-1)(n-2) = 210
7x6x5 = 210
nC3 = 35
7C3 = 35
So If there are 35 combinations, 7 colors are available.
Thank you!
