You can put this solution on YOUR website!
I got a feeling you meant the following:
\n" ); document.write( "p(X=0)=.25,
\n" ); document.write( "P(X=1)=.125
\n" ); document.write( "P(X=2)=.125 and
\n" ); document.write( "P(X=3)=.5, right?
\n" ); document.write( "The cumulative distribution function is
\n" ); document.write( "F(X = 0) = 0.25
\n" ); document.write( "F(X = 1) = 0.375
\n" ); document.write( "F(X = 2) = 0.5
\n" ); document.write( "F(X = 3) = 1.
\n" ); document.write( "It's easy to plot the probability mass function for this distribution.

\n" ); document.write( "
\n" );
