In the set of all past due accounts, let the event A mean the account is between 31 and 60 days past due and the event B mean the account is that of a new customer. The complement of A is a. all new customers. b. all new customers whose accounts are between 31 and 60 days past due. c. all accounts fewer than 31 or more than 60 days past due. d. all accounts from new customers and all accounts that are from 31 to 60 days past due.

c. all accounts fewer than 31 or more than 60 days past due.

Step-by-step explanation:

The Universal Set is the set of all past due accounts.

Event A = the event that the account is between 31 and 60 days past due.

Event B = the event that the account is that of a new customer.

Therefore, the complement of A will be the event of all the accounts fewer than 31 or more than 60 days past due.

The correct option is C.
