From 10 to 99, there are 90 of them.\r\n" ); document.write( "\r\n" ); document.write( "You also know that every other number is an odd number, so exactly half of the 90 numbers are odd numbers. \r\n" ); document.write( "\r\n" ); document.write( "So there are 45 odd 2-digit numbers.\r\n" ); document.write( "\r\n" ); document.write( "Probability = (number of favourable events)/(number of total events possible)\r\n" ); document.write( "\r\n" ); document.write( "Here total events possible = 90 (there are 90 possible 2 digit numbers)\r\n" ); document.write( "Total favorable events = 45 (only 45 of the 2 digit numbers are odd)\r\n" ); document.write( "\r\n" ); document.write( "So the probability = 45/90 = 1/2\r\n" ); document.write( "\r\n" ); document.write( "Hope this helps :)\r\n" ); document.write( "\r\n" ); document.write( "\n" ); document.write( " |
