As we learnt

 

Properties of Binomial Theorem -

 

Sum of the binomial coefficients of the odd term is equal to sum of the binomial coefficients of even term and each is equal to 2^{n-1}.
 

- wherein

c_{0}+c_{2}+c_{4}----

= c_{1}+c_{3}+c_{5}----

= 2^{n-1}

 

 

 \binom{5}{0}+\binom{5}{2}+\binom{5}{4}=\binom{5}{1}+\binom{5}{3}+\binom{5}{5}= \frac{2^5}{2}= 2^{4}
