What is the probability that an Amazon.com visitor
\n" ); document.write( "will buy eight books, if we are given the following probabilities
\n" ); document.write( "

\r\n" );
document.write( "\r\n" );
document.write( "Let P(8 or more) = x\r\n" );
document.write( "\r\n" );
document.write( "x        P(x)\r\n" );
document.write( "0        0.327 \r\n" );
document.write( "1        0.206	\r\n" );
document.write( "2        0.07		\r\n" );
document.write( "3        0.097\r\n" );

document.write( "6        0.01\r\n" );
document.write( "7        0.24\r\n" );
document.write( "8 or more  x\r\n" );
document.write( "--------------\r\n" );
document.write( "         1.000\r\n" );
document.write( "\r\n" );
document.write( "The sum of all probabilities must have sum 1\r\n" );
document.write( "\r\n" );
document.write( "0.327+0.206+0.07+0.097+0.028+0.022+0.01+0.24+x = 1\r\n" );
document.write( "                                           1+x = 1\r\n" );
document.write( "                                             x = 0\r\n" );
document.write( "\r\n" );
document.write( "So the probability of buying 8 or more is 0.\r\n" );
