3-A bank has 3 branches: A, B, and C. Branch A does 50% of the business, branch B does 30% of the business, and branch C does 20% of the business. If someone goes to branch A, the chance they are depositing money is 20%. If someone goes to branch B, the chance they are depositing money is 40%. If someone goes to branch C, the chance they are depositing money is 60%.
