18% of the 50 elements are green or 9 elements.
\n" ); document.write( "However, the sum of probabilities should be 1.
\n" ); document.write( "Is there another color that has 0.1 or are any of the values incorrect.
\n" ); document.write( "Without another contribution, the probability distribution is not valid.\r
