Pls help me with this problem:-

A license plate has 3 ltrs & 3 digit in tht order. A witness to a hit & run accident saw the first 2 ltrs. & the last digit. If the letter & the digit can be repeated, how many number license plates must be checked by the police to find the culprit?

Also, pls. let me know how many problems involving statistics, probabilities, permutation & combination are involved in GMAT? If you have any question bank for this, pls. do forward.

thanks,

10 choices for the second digit.

26*10*10=2600.

P.S. I think at max 1-2 questions from each area (statistics, probabilities, permutation & combination).
