A state requires that all boat licenses consist of the letter A or M or P or S followed by any five digits. What is the number of groups of letters and numbers available for boat licenses?

First position   4 choices   ( A M P S)

  then 5 digits     10000 choices   (00000 through 9999)

      4 * 10 000 = 40 000 licenses available
