Another very interesting problem
If the candles were all of a different color, then the first candle (randomly chosen) would be 7. The second candle would be any one of 6. Third would be any one of the remaining 5, then 4 then 3 then 2 then 1
The abbreviated way of writing that is 7! which means that the number of different ways would be
7*6*5*4 *3*2*1
However this problem is not that simple The complexity comes from the fact that there are colors that are duplicated.
That event is handled by dividing 7! /by 3! and another 3!
The result is 140
3! = 3*2*1 = 6
So you would take 7! and divide by 6*6
5040/36 = 140
This problem is much more difficult than any of the others.

Step-by-step explanation:
g (f (4)) = -24
Explanation:
g(n) = 4n
f (n) = -2n + 2
f(4) means n = 4
f(4) = -2(4) + 2
f(4) = -8 + 2
f(4) = -6
g (f (4)) means n = f(4) = -6
g(-6) = 4(-6)
g(-6) = -24
g (f (4)) = g(-6)
Therefore, g (f (4)) = -24
