Best ResponseYou've already chosen the best response.0The choice for the no. of ways in which the first two letters can be chosen from available 25 letters = 25P2 = 600 And, the no. of ways in which the four digits can be chosen from available nine other digits = 9P2=72 Now, The no. of passwords possible are = 600 * 72 = 43200

Best ResponseYou've already chosen the best response.0If the first position can be filled with any of the 25 letters, then there are 25 ways of performing this first action. Now for the second letter, also any of the 25 letters can be used, hence there are 25 ways of performing this second action. Then there are 25 X 25 ways of picking two letters.
