We want to form a license plate using 4 letters (A-Z) followed by 3 numbers (0-9). Both may be used more then once. A license plate is chosen randomly. What is the probability that the letter A is not used?
\n" ); document.write( "----
\n" ); document.write( "Number of plates with no \"A\" = 25^4*10^3
\n" ); document.write( "----
\n" ); document.write( "Number of plates with no restriction = 26^4*10^3
\n" ); document.write( "-----------------------------------------------------
\n" ); document.write( "P(letter A not used) = 25^4/26^4 = 0.8548
