If `.^nC_8=^nC_2`, find `.^nC_2`

If .^nC_30=^nC_4 , find n

If .^nC_9=^nC_8 find .^nC_17

If .^nC_12=^nC_8 , find .^nC_17 and ^22C_n

If "^nC_5= ^nC_12 find n.

If "^nC_10 = ^nC_5 find "^nC_14

If .^nC_8=^nC_6 , determine n and hence .^nC_2

"^mC_1=^nC_2 , then -

If .^nC_10= ^nC_12 , determine n and hence .^nC_5

If .^nC_0,^nC_1,^nC_2,.....^nC_n are frequencies of n+1 observations 1,2,2^2,.....2^n such that mean is 729/2^n then value of n is:

If ^nC_4, ^nC_5 and ^nC_6 are in A.P. then the value of n will be (A) 14 (B) 11 (C) 7 (D) 8
