According to pap's analysis to each bank:
1. Employ two security guards at $20k each per year = $40k per year
2. Based on one robbery every 10years = $30k (Holland Village)
Cost of employing security guards - loss = ($400k-$30k)
Conclusion: Bank need not employ security guards as it gains $370k per year despite risk of robbery at the bank
