If ^6C2 = ^6CX then find possible values of x.(a) 2(b) 4(c) 2 and 4(d)

1.	If ^6C2 = ^6CX then find possible values of x.(a) 2(b) 4(c) 2 and 4(d) 3The question was asked in final exam.My doubt stems from Combinations in section Permutations and Combinations of Mathematics – Class 11
Answer» CORRECT choice is (C) 2 and 4 Easiest EXPLANATION: We KNOW, ^nCp = ^nCq =>either p = q or p + q = n. => either x=2 or x+2=6 => either x=2 or x=4.
