Suppose an opaque jar contains 5 red marbles and 10 green marbles. Two marbles are picked at random from the jar without replacing the first one.
\n" ); document.write( "
\n" ); document.write( "The probability of getting a green marble first and a red marble second is:
\n" ); document.write( "(5/15)(10/14) = 50/(210) = 5/21
\n" ); document.write( "-------- \r
\n" ); document.write( "\n" ); document.write( "The probability of getting one green and one red marble is:
\n" ); document.write( "# of red/green pairs = 5*10 = 50
\n" ); document.write( "# of random pairs:: 15C2 = (15*14)/(1*2) = 15*7 = 105
\n" ); document.write( "P(red/green pair) = 50/105 = 10/21
\n" ); document.write( "------------
