(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

a) How many entries can be chosen independently, in a symmetric matrix of order n?

b) How many entries can be chosen independently, in a skew-symmetric matrix of order n?

2. Relevant equations

3. The attempt at a solution

All I know are the definitions of a symmetric and a skew symmetric matrix.

I don't understand the problem, what does chosen independently mean? Is this a sum of some sort? Any hints are greatly appreciated!
