Two distinct even numbers are selected at random from the first ten even numbers greater than zero. What is the probability that the sum is 30?
\n" ); document.write( "FIRST TEN EVEN NUMBERS >0 ARE
\n" ); document.write( "2,4,6,8,10,12,14,16,18,20....
\n" ); document.write( "SUM IS 30 IT IS GIVEN ..THAT IS EXACTLY EQUAL TO 30....SO
\n" ); document.write( "START WITH 2..PROCEED FROM LEFT TO RIGHT AND CHECK
\n" ); document.write( "WITH 2....NONE
\n" ); document.write( "WITH 4...NONE
\n" ); document.write( "WITH 6...NONE
\n" ); document.write( "WITH 8...NONE
\n" ); document.write( "WITH 10....1.....
\n" ); document.write( "WITH 12....1
\n" ); document.write( "WITH 14....1
\n" ); document.write( "WITH 16...NONE..SINCE IT IS ALREADY CONSIDERED UNDER 14
\n" ); document.write( "WITH 18...NONE..SINCE IT IS ALREADY CONSIDERED UNDER 12
\n" ); document.write( "WITH 20...NONE..SINCE IT IS ALREADY CONSIDERED UNDER 10\r
\n" ); document.write( "\n" ); document.write( "SO THERE ARE ONLY 3 COMBINATION POSSIBILITIES OUT OF 10C2 TOTAL COMBINATIONS
\n" ); document.write( "PROBABILITY = 3/10C2=3*8!*2!/(10!)=3*2/(10*9)=1/15 \n" ); document.write( "
\n" );
