From the historical data, the firm has determined the following
transition matrix:
  
| 
 New Account  | 
 1M Overdue  | 
 2M Overdue  | 
 3M Overdue  | 
 Paid  | 
 Bad Debt  | 
|
| 
 New Account  |

 0.0  | 
 0.0  | 
 0.0  |

 0.0  | 
 1.0  | 
  
For example, if an account is two months overdue at the beginning
of a month, there is a 40% chance that at the beginning of next
month, the account will not be paid up (and therefore be three
months overdue) and a 60% chance that the account will be paid up.
It is assumed that after three months, a debt is either collected
or written off as a bad debt. Once a debt is paid up or written off
as a bad debt, the account is closed, and no further transitions
occur.
What is the probability that a new account will eventually be
collected?
| A. | 
 0.700  | 
|
| B. | 
 0.964  | 
|
| C. | 
 0.880  | 
|
| D. | 
 0.036  | 
|
| E. | 
 0.940  |
