Poisson with parameter 10. counts, proportional to time, can be theoretically infinite
\n" ); document.write( "e^(-10)^10^5/5!=0.0378
\n" ); document.write( "at least 2 units, look at 1 unit and 0, get those probabilities and subtract from 1.
\n" ); document.write( "p(0)=e^(-10)=0.000045
\n" ); document.write( "p(1)=e^(-10)10*1/1!=0.00045
\n" ); document.write( "These two add to 0.0005
\n" ); document.write( "probability at least 2 is 0.9995
\n" ); document.write( "
\n" );
