Answer:
<em>=84</em>
Step-by-step explanation:
If we have n types of elements and we have to choose r elements from then, then we have C(n+r-1, r) r-combinations.
To choose 6 different candles,
n=4(4 types of candles), r=6(no of candles to pick)
=C(4+6-1,6)
=C(9,6)
= 9! / (9-6)! (6!)
= 9!/ 6! 3!
=84
