A signal can be sent from one location to another by running different colored flags up a flagpole, one above the other. There are 15 different colored flags to choose from but only 6 flags will be flown. Find the number of different signals consisting of 6, if the first flag must be purple.
If the first flag is purple then the number of different signals consisting of 6 flags is
