How many license plates are possible to make if (a) digits and letters can be repeated, (b) and digits and letters cannot be repeated.
\n" ); document.write( "a) 4 digits followed by 2 letters
\n" ); document.write( "b)6 digits followed by 3 letters\r
\n" ); document.write( "\n" ); document.write( "Label a digit as d and letter as l
\n" ); document.write( "a) ddddll
\n" ); document.write( "If you can repeat:
\n" ); document.write( "nine options for each d and 26 options for each l
\n" ); document.write( "9*9*9*9*26*26=4435236
\n" ); document.write( "Cannot repeat:
\n" ); document.write( "nine options for the first d, eight for the second, seven for the third, and six for the fourth; 26 for the first d and 25 for the second
\n" ); document.write( "multiply it all:
\n" ); document.write( "9*8*7*6*26*25=1965600
\n" ); document.write( "b)ddddddlll
\n" ); document.write( "Repeat:
\n" ); document.write( "Use same way (nine options for each digit and 26 for each letter)
\n" ); document.write( "9*9*9*9*9*9*26*26*26=9340607016
\n" ); document.write( "Cannot repeat:
\n" ); document.write( "Same pattern:
\n" ); document.write( "9*8*7*6*5*4*26*25*24=943488000
\n" ); document.write( "Please let me know how helpful was this \n" ); document.write( "
