\n" ); document.write( "Number of jobs 1 2 3 4
\n" ); document.write( "Probability .2 .3 .4 .1
\n" ); document.write( "Find the contractors expected profit per month.
\n" ); document.write( "---------------
\n" ); document.write( "Expected number of jobs is 1*0.2 + 2*0.3 3*0.4 + 4*0.1 = 2.4 jobs
\n" ); document.write( "Expected Profit would be 2.4*3000 = $7200
