p(nixon) = 242/2016 = .12, n = 3
\n" ); document.write( "TI syntax for P(x-value) is binompdf(n, p, x-value).
\n" ); document.write( "a)P(x = 3) = (3, .12, 3)
\n" ); document.write( "b)P( x = 0) = (3, .12, 0)
\n" ); document.write( "|
\n" ); document.write( "c) P(x <=2)
\n" ); document.write( "I syntax is binomcdf(n, p, largest x-value) for binomial ≤ cumulative probability
\n" ); document.write( "P(x <=2) = binomcdf(3, .12, 2)
\n" ); document.write( "d) One with smallest probability \n" ); document.write( "

\n" );
