Correct Answer - Option 1 :
Equal
Calculation:
The coefficients of xp and xq in the expression of (1 + x)p + q
We know, yp+1 = p + qCp xp and yq + 1 = p + qCq xq
Coefficient of xp = p + qCp = [p + q]!/p!q!
and
Coefficient of xq = p + qCq = [p + q]!/p!q!
∴ Coefficients of xp and xq in the expression of (1 + x)p + q are equal.
