Fewer than 5 customers.
\n" ); document.write( "Do probabilities of 5,6,7 and subtract those 3 probabilities from 1.
\n" ); document.write( "for 5: 7C5*0.85^5*0.15^2=0.2097
\n" ); document.write( "for 6: 7*0.85^6*0.15=0.3960
\n" ); document.write( "for 7: 0.85^7=0.3206
\n" ); document.write( "they add to 0.9263
\n" ); document.write( "so the answer is the complement or 0.0737
\n" ); document.write( "
\n" );
