The following list gives the coefficients for the binomial expansion of (x + y)10. what is the value of b? 1, 10, 45, 120, 210, 252, 210, b, 45, 10, 1 a1 b10 c45 d120

1, 10, 45, 120, 210, 252, 210, B, 45, 10, 1

Do you see how the coefficients are symmetrical ?

252 is in the center, the coefficients are combinatorial.

C(1,10) C(2,10) C(3,10)

B = 120

The correct answer is D. 120
