Fidelity records the number of X-Trails sold each day. This data is used in calculating the following probability distribution of daily sales:\r

\r\n" );
document.write( "The word \"cumulative\" reminds you of 'accumulating', so you 'accumulate'\r\n" );
document.write( "the P(x)'s as you go, by adding all the previous values to each one.\r\n" );

document.write( "                x       P(x)   CDP(x)\r\n" );
