\n" );
document.write( "Note: The probability of x successes in n trials is: 
\n" );
document.write( "P = nCx*  where p and q are the probabilities of success and failure respectively. 
\n" );
document.write( "In this case p = .5 and q = .5 
\n" );
document.write( "nCx = 
\n" );
document.write( "Assume sales calls are independent and the employee is doing 2 sales calls
\n" );
document.write( "P(at least one of the two sales calls is successful) = 1-P(none)= 1 - (.5)^2
\n" );
document.write( "P(at least one of the two sales calls is successful) = .75 \n" );
document.write( "

\n" );
