\r\n" );
document.write( "Total number of balls = 9\r\n" );
document.write( "Therefore total number of possible outcomes = 9\r\n" );
document.write( "Probability is the number of favourable outcomes divided by number of total \r\n" );
document.write( "possible outcomes.\r\n" );
document.write( "a) Red and even number\r\n" );
document.write( "No. of favourable outcomes = \r\n" );
document.write( "Number of balls that satisfy this condition = 2 (2 and 4)\r\n" );
document.write( "Therefore probability = 2/9\r\n" );
document.write( "b) Red OR Even number\r\n" );
document.write( "No. of favourable outcomes = \r\n" );
document.write( "Number of balls that satisfy this condition = 6 (1,2,3,4,6,8)\r\n" );
document.write( "Therefore probability = 6/9 = 2/3\r\n" );
document.write( "c) White OR odd number\r\n" );
document.write( "No. of favourable outcomes = \r\n" );
document.write( "Number of balls that satisfy this condition = 7 (1,3,5,6,7,8,9)\r\n" );
document.write( "Therefore probability = 7/9\r\n" );
document.write( "Hope you got it :)\r\n" );
