You can put this solution on YOUR website!
this is a uniform function with pdf f(x)=1/(b-a)\r
\n" ); document.write( "\n" ); document.write( "the cumulative distribution function is
\n" ); document.write( "0 for x<=1
\n" ); document.write( "(x-a)/(b-a) for 1 < x<3 (integrate the pdf (1/b-a) between a and b or 1 and 3
\n" ); document.write( "1 for x>=3\r
\n" ); document.write( "\n" ); document.write( "probability x <= 1.6 is 0.6/2.0 or 30%
\n" ); document.write( "probability of the second (doesn't format when I write it mathematically) is 0.5/2.0 or 25%
