\n" ); document.write( "Multiply the value of each outcome by its probability and add all those products.

\n" ); document.write( "The probability of each number coming up on the die is 1/6.

\r\n" );
document.write( "  outcome  value  probability  product\r\n" );
document.write( " --------------------------------------\r\n" );

document.write( "                             ------\r\n" );
document.write( "             expected value:  33/6 = 5.5
