There are 3 possible scenarios:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Scenario 1) Both roses are red\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "P(Both Red) = P(Red)*P(Red) = (3/12)*(2/6) = 6/72 = 1/12\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-------------------------------------------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Scenario 2) Both roses are pink\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "P(Both Pink) = P(Pink)*P(Pink) = (4/12)*(2/6) = 8/72 = 1/9\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-------------------------------------------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Scenario 2) Both roses are white\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "P(Both White) = P(White)*P(White) = (5/12)*(2/6) = 10/72 = 5/36\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now add up all the probabilities:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "1/12 + 1/9 + 5/36 = 3/36 + 4/36 + 5/36 = (3+4+5)/36 = 12/36 = 1/3\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the probability that one rose chosen from each vase will be the same color is 1/3
\n" ); document.write( "
\n" );
