You can put this solution on YOUR website!
probability of 0 errors for this Poisson distribution is e^(-0.5)*0.5^0*0!=0.6065
\n" ); document.write( "-
\n" ); document.write( "for 10 pages is is 0.6065^10=0.0067,
\n" ); document.write( "Also can use Poisson of parameter 5 and looks at probability of 0 errors. Just multiply the Poisson parameter by 5 pages, since the Poisson parameter is proportional to the amount of time or chances.
\n" ); document.write( "this is e^(-5)*5^0*0!=0.0067
\n" ); document.write( "
\n" );
