I use following definitions:

• Recall tells you how much of the 1’s you can find.
• Precision tells you how much junk there is in your predicted 1’s.
  
  

Knowing this, it is straightforward to calculate these metrics:

• Recall: correctly predicted 1’s / all 1’s = TP / (TP + FN)
• Precision: correctly predicted 1’s / all predicted 1’s = TP / (TP+FP)
