Since \"a mini license plate for a toy car MUST consist of a number followed by two letters\" then the following are the only arrangements allowed for the letters:
\n" ); document.write( "CC, CA, CR, AC, RC, AA, AR, RA, RR The sample space.
\n" ); document.write( "There are 5 containing a C out of 9.
\n" ); document.write( "5/9 the exact probability of creating a mini license plate with a C.
\n" ); document.write( ".
