Answer 2

Answer:

Value of n is 18.

Step-by-step explanation:

We are given that   $^nC_{6}=^nC_{12}$

We have to find Value of n

We use result of Combination, which says that

If   $^nC_x=^nC_y$

then $x=y$ or $n=x+y$

here, x = 6 and y = 12

6 ≠ 12

So, n = 6 + 12 = 18

Therefore, Value of n is 18.
