I have N objects which can have either 1 or both properties, A & B. I want to know if having property A raises the chance of having property B. 

My data is:

 ![data](https://i.sstatic.net/bNwCw.png)

Where S means they have the property, and N means they dont (ie, 263 objects have A & B, while 188 have B but not A). 

What is the correct test to see whether having property A raises the chance of having property B?

I guess I can just use a 2 proportion test , but I feel like theres somethnig more specialized to this problem...

Thanks!
