document.write( "There are 6 possible outcomes 1, 2, 3, 4, 5 an 6 of each roll.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Three outcomes (2, 3, 5) are prime numbers, the other three are not.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the probability DO NOT get a prime number in each roll is .\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the probability DO NOT get a prime number in all 5 rolls is   =  = .\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the probability to get at least one prime number in 5 rolls is  the COMPLEMENT to it:\r\n" );
