document.write( "There are 50 numbers from 1 to 50 inclusively.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Half of them, 25, are odd.  All primes (except of 2) are among odd numbers.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "There is only one prime which is even: it is 2.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, 25 + 1 = 26 numbers of 50 are  EITHER  an odd  OR  a prime.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The rest 24 = 50 - 26 are  NEITHER  an odd  NOR  a prime.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus your answer regarding the probability is  =  = 0.48.\r\n" );
