\n" );
document.write( "probability is 0.62 that a high school valedictorian graduates from college as cum laude
\n" );
document.write( "P = nCx*  where p and q are the probabilities of success and failure respectively. 
\n" );
document.write( "In this case p(cum laude)= .62 & q = .38  and n = 5
\n" );
document.write( "random sample of 5 valedictorians
\n" );
document.write( "P(x = 4) = 
\n" );
document.write( "P(x  ≤ 3) = 1 - P(x=4) - P(x=5) = 
\n" );
document.write( "P(x  ≥ 1) = 1 - P(0)=  \n" );
